I have used the jmp-1for about 20 yrs! I absolutely love it and if you spend time to tweak your sound to your style you will absolutely gel with it and not ever want to play any other amp!
I've had the Jmp1 for many years and it's a killer classic Marshall tone. Good speaker simulation for direct recording. Works well with a tube power amp or in a tube amp effects loop. I recommend it if you are a fan of the sound of the 90's
Been direct with a JMP-1 since 2006, before that, used one with two 1978 heads, that Phil Wells from Marshall "modded" for me. £8 (back in 2002!) where the mod is for them to add a power amp input to the heads. Running one of my JMP-1's L+R Master Outs into each head then into two 4x12's was totally it for me for years... when I went solo, I simply just plugged the JMP-1 direct into the mixing desk. played on stages in front of thousands using nothing more than a stock JMP-1 direct to desk. Marshall really nailed the speaker simulator and just got it right with this thing. They had to discontinue the JMP-1 due to the changes in EU solder laws (switched from lead based to water based) and that would have meant completely updating their solder baths, and all the manufacturing process, so they stopped making it. Such a huge shame. You can pick them up cheap on eBay for a song right now. AxeFX, Kemper, tried them both, kept coming back to OD1 on the JMP-1. Nothing quite beats it in a live setting. In the studio I still use Amplitube 3 and 4, but more recently I am using a JMP-1 again. Marshall should bring out a JMP-2, with USB and an onboard tuner, and effects. The CODE was absolute rubbish sadly, and for those of us who can't lug about a huge transformer laden valve amp and cab anymore, this really is a good alternative. Despite owning numerous JMP-1's, my main one, I've had since 1997! used it every day, never went wrong, never crapped out on me. If you know how to use them (Like with any gear I guess) you can get some of the best tones around.
I've been looking at a JMP-1 since they aren't too expensive on Reverb and I'm a big Iron Maiden (and Def Leppard as well, although I didn't know they used these too until recently). It seems like it would be fun to have next to my ADA MP-2 that I bought new 25+ years ago. Right now, it seems the only folks really using rack gear are large touring bands, so unfortunately I don't think Marshall would think there is enough of a market for a JMP-2, although I agree I would consider one.
Classic Marshall sound, all valve / tube, and easily modernized with an additional distortion pedal - I use the Tim Pierce overdrive. Lovely how far you can get into what Dave Friedman achieved when modernizing the Marshall sound. Cheers from Germany!
Thank you a million times. Nobody has done an in-depth look at this thing, and I’ve been interested in them ever since I discovered that Def Leppard have used them live forever (they only very recently switched to all Fractal live rigs). Every time I saw Leppard, both Phil and Viv were playing these, and the sound they got with them was always perfection to me. Marshall should have kept making this.
I used the JMP-1 with a Bradshaw Switcher. Eventide H3000, Lexicon PCM 81, 2 SDE 3000’s, Pro VLA compressor & a Marshall 9200 or the EL 34 100/100. Compared to all my plexi’s and the old Marshall’s I have, these preamps will make you some cash. Many have also used these. They deliver whatever you want.
Love the Marshall JMP-1 And even more favoritley absolutely love my ADA MP-1. I actually have the settings Nuno Bettencourt used with the ADA MP-1 if anyone would like them.
I owned one of these for about 20 years with a Marshall 9200 power amp (5881 tubes). I bought them new and they served me well for a long time. It was an amazing rig. I loved the 5881 tubes. It really became fat, chunky and amazing at stage volumes in larger venues. I would get a sound somewhere between Michael Schenker and George Lynch (Tangled in the Web) just using the preamp gain and the power tube gain. The cool thing with a rig like that is that you can push the volume of the power amp separately from the preamp gain, so you can find your tone with that much more control. Another great thing is that I could place something like a TC Electronic G Force in the line between the JMP-1 and the 9200 power amp and that was also amazing. This also gave me the option of splitting the signal into stereo out and using both sides of the 9200 power amp separately and using stereo effects. I also used a TC Electronic D Two before I got the G Force, but I don't remember if that was run the same way or actually in the effects loop. I loved and used the midi in the JMP-1, changing amp channels and effects simultaneously, although I primarily used one aggressive amp sound and used the volume on my Les Paul to adjust that sound. On a lot of my midi settings, I had it so that the amp would stay the same and the effects would change. The JMP-1 was really well designed. I wish that they kept updating this model as they went into the higher gain era. I don't know if this is correct, but as I understand it, Marshall could no longer make the JMP-1 because of something internal that new environmental regulations made illegal. Not sure what that would have been or why there would not be an alternative. The closest amp that I have found to be a successor to that rig is the JVM410HJS. Just a great amp. It had to be for me to sell my JMP-1 and 9200.
Another thing that I forgot to mention is that I placed Mesa 5881 Tubes in the 9200 and Mesa gives you the option of early, mid or late breakup tubes. I always went with mid. I would normally put my 9200 volumes around 6 or 7 and then control the volume of the whole rig via the volume knob on the JMP-1. I still miss that rig.
Grab yourself a cup of coffee and read Leon’s comment section pertaining to the JMP-1. Thank you good sir for your genuine enthusiasm for all things guitar and gear related. You’ll be at 200k subs before you know it. Nobody is more deserving. This channel never ceases to impress.
I bought my first one in the early 2000's and still have it. I bought a second one in case something happened to the first one. Love them. Od 2 is great by itself, of 1 with a boost in front sounds like a 800 from the 80. They great. I Never understood why they didn't make a head that was based off of this. 100 channel fully programmable head...would have been great too.
After I saw this video,I just bought one. It sounds fantastic. Modeling is very advanced but tube stays tube. JMP-1 -> MOOER Radar (4x12") -> Interface. Great, great sound.
I currently play a JCM-800. I am thinking about switching up to this preamp but I would love to hear a side by side comparison!!! The band has switched to in ear monitor system with each of us having our own mix and individual control of our own mixes. Lugging the amp around isn't really practical anymore.
Aaah the good ol’ JMP1! Used to have a rig consisting of the JMP1, a Digitech GSP2101, the Marshall 9200 dual monobloc and a Marshall 1960 4x12 cab set to stereo. Sweet memories!
Leon Todd Haha, it was huge and very heavy. Drove it around in the back of my moms ‘84 Toyota Starlet. Hardly could steer it. 😂 But the sounds, though! I immediately recognized the sound! Great vid, Leon!
EMG ENT Yeah! The 2101 was basically the the first modeler and indeed, the FX (not the preamp) are still fantastic...especially the bottomless chorusses and multitap delays...
EMG ENT I think you’re right, wasn’t that a mod? Anyway, just came across a second handed 2101...120 euro...I think I’m gonna buy it and make a vid with it. :)
I wouldn't say the GSP 2101 had a bad preamp at all! In fact the Saturated tube mode is electrically very similar to the Engl e530 preamp. The best way to take full advantage of it is to make all your algorithms with the 5 band parametric eq and/or the 10 band graphic the first modules in the alg and run the unit 100% wet.
Greetings from Cali, Colombia... I have the JMP1 for more than 10 years now, and i still in LOVE, it is so vesatil, intuitive, sounds GREAT, in simple words, WHY MARSHALL TAKE THIS PREAMP OUT OF PRODUCTION??? Guitarist NEEDS a real great sound and this preamp it have EVERYTHING for a great tone... My main guitar rig is, this Marshall JMP1 midi tube preamp, Peavey Tube Power Amp Classic Series 50/50, Alesis MidiVerb 4, Line 6 X2 wireless guitar system, phonic power conditioner and a Marshall Lead 1960 4x12 A cabinet and the Peavey Professional Midi Foot Control... As i already said, after more tgan 10 years with this rack, I STILL IN LOVE!!! ❤ Well THANKS for this video and for read my comment, if anyone here wants to follow me, go to my official FB FanPage, here in youtube, or at instagram as Adrian Oleas or my Band Darkempire... See you guys!!! 🤘😎🎸🇨🇴
To get an AC/DC 'Low gain' sound for instance...would one use a clean channel gained up high OR OD1 with gain on say 1 or 2 ?...OR does this unit simply not do those 'Classic' Marshall sounds ( Zep, Lizzy, Purple, AC/DC etc) I understand this rack came out when higher gain was the rage.
I used to record EVERYTHING through a jmp-1. Bass ,vocals ,overheads and of course guitar. People used to ask me what expensive mic pres I used cause everything sounded so juicy!
@@LeonTodd yup. I used battery power on some nice handheld senheiser vocal mics through the jmp-1 clean channel. Best tube pre/ eq combination for warmth with sizzle.
@@LeonTodd I also used to run the entire mix through it in mono! Hahaha, assign it to a bus and run it up slowly until it added a little something, always checking for phase of course. You'll love Todd. Just think of it as a tube channel strip. With an optical compressor on the end it ,EVERYTHING sounds good through it.
Years ago I got two Kitty Hawk Cabs with 4x12 G12T75 from a friend of mine for a friendship prize. He himself had two more. Half a year ago, one broke and he asked if I wanted to give one back. What can I say? Friends will be friends. And so I sold one back for the same price.
I still have all major 3 preamps of the 80s-90s. The JMP-1, the ADA MP-1 3TM and the Triaxis. Both the ADA and the Triaxis are Beasts on sound and for Metal Chunky tones, you can't go wrong. My Triaxis is my go-to "Metallica-Boogie Thrash" rig, my ADA is my go-to "Marshall-on-steroids" Thrash rig. So for years, JMP-1 (being softer and all) just wasn't cutting it for me. HOWEVER, recently I decided to setup a "Malmsteen" rig...Since a "Plexi" is out of the question (money+volume), I used the JMP-1 with a 20/20 Marshall power amp to get a Plexi-sound and used the famed DOD250 in front. And OH-MY-GOD, it just couldn't get any better. I am amazed on how convincing the JMP-1 as a "cranked Plexi" is....Compared it with all Plexi sound samples out there, it does the job brilliantly!! And with the DOD250 in front, its heaven. Early Malmsteen sounds (Marching out-Trilogy etc.) are SO spot on, you can only tell its NOT Malmsteen by.....my playing :)
Most versatile with cleans and all Marshall sounds in one box and still popular with touring stars. Why is it discontinued? Rack units went out of fashion?
This unit had some fuckin BRILLIANT CLEAN TONES!! Fender and Roland Jazz Chorus 120 CLEAN TONE TYPES!! I owned one for near 15 years and when it finally died I was told Marshall bailed on the line pf them because of components...rather than doing a whole redo pf components they discontinued the unit.. Gainstahes were not the best but the cleans were AWESOME
@Schmoolie Deninostein Holy shoot... I knew Trent Reznor used one. CORGAN NOW? I think I'm sold. Corgan's live sound back then was pretty sweet. A little chaotic and 90's, but pretty sick. Also Iron Maiden uses them still, if I'm correct. Gotta get that cash, before they jump in price again.
Awesome cleans for sure. But I honestly think this amp's real charm is the OD channels. They have such a unique bark and growl to them that I usually only hear from really expensive amps from Germany.
Hi there. Alot of the players I like, Phil Collen, Ace Frealey Billy Gibbons tend to use this for live work. Are these preamps more for live use than as a general amp? I love the sound of this amp and would want to use it as my sole amp
In 2019 i got one JMP-1 Stock. I'm just a bit worry about the backup battery soldered at 2 or 3 terminals on the pcb... Mr. Leon Todd would throw some light about this issue ?! Thanx. Cheers from Viamao City - RS BRAZIL 🇧🇷
I'm not too familiar with any of the internal specs unfortunately. Might be wrth writing to Marshall support and seeing if they can point you in the right direction.
@@LeonTodd Mr. Todd: thank you anyway! I'm glad with your answer and i'll try contact Marshall support to find some option for this situation. Leakage bateries could ruin the pcb, and make the whole device useless, if it not replaced. Love your channel and your songs!!!! Excuse for my slop english... kkkk... Cheers from Viamão City, RS Estate 🤘😃🎸🇧🇷Brazil.
Just bought one five days ago. Already trying to work out where it has been all my life! Did and album in lockdown and I really wish I had this to do the guitars with as it sounds so good!
Came to check this out because A.) Stephen from Deftones used/uses this preamp and B.) I wanted to see how this compares to the STL Tones Amphub version, the Brit J1. Pretty close comparison, and I think I might get a used JMP-1 for my live rig. absolutely love the way it sounds with a boost at the front in OD2!
Leon, Tremendous channel! I’m wondering your feelings on this versus an Axe-fx III (which I own)? I’m thinking of maybe going the Synergy route or this on the front end so I can use pedals to overdrive the front, which you obviously can’t do on the Axe. I also own a Friedman be-100 which I can’t seem to gel with as it’s a bit too stiff for me. Thanks for what you do!
I have a special request: can you do a follow-up short video using this JMP-1 unit with a JB/Jazz humbuckers 25 frets guitar (not a Gibson nor a Stratocaster) to replicate Dave Mustaine's rhythm tone. I know he used the JMP-1 a lot in the past (early albums played LIVE) powered by the Marshall 9100 block amp. What I'd like to get are the JMP-1 settings you would use to replicate his tone as ''best'' as you can. I know it's kind of hard because he has always used a lot of effects/EQ ''mystery boxes'' to carve his sound, but if you could at least, give me a base setup, that would be great. Cheers!
Leon what is meant by line level you mention at the start. I have this gear and want to rig it up , presume you mean both the switches are matching so -10db or +4 Thanks
Great video. I dig your playing and presentations. I had one of these along w a Roland RSP-550 back in the ‘90s. Played it through a Boogie Mark IIB combo. Sounded great but wish I’d tried it through a EL34 power amp back then after hearing this video. I’m thinking of getting another (which is how I landed here). It’ll be mainly for recording and I’m wondering how the DI and speaker simulators sound. I’ve got the OX Amp Top Box; too but all my amps are 6L6 still. So NOW what...!!?? 🤔
Get an Atomic Amplifire for a little bit more money - sounds way better direct. Or pony up some extra cash and get a Fractal AX8 or FM3, the JMP1 models in them are dead on.
Cuppa coffee and gear talk. Great way to start the day! Right now I’m using an XTS Atomic Overdrive for the Marshall sound. Excellent for the JCM800 sound and more. I like their stuff. I’m new to recording electric. Everything before was solo acoustic, which is pretty simple compared. Interesting you’d mention the Fractal stuff. I checked out your vids on Kemper and/or Fractal. Friend of mine picked up the Kemper rack after checking them out, too. Monster engine. I ended up getting that UA OX. I’m pretty attached to my pedals and amps, as is. But so far I’m not getting my gear to translate well through it to my DAW. Especially the distortion stuff. I’m giving it a little more time but might do an exchange. I was considering the JMP-1 through the OX but see above. I’ll check out the Amplifire. Thanks for the tip. Btw: I really did love that JMP-1 in the ‘90s except for one very big thing: latency. Three man band with lots of patch changes...that split second of silence drove me bonkers. So cool that you reply, Leon. Good day to ya!
I really like mine. Ya gotta remember that when they came out in the early '90s, they were pretty "big" for the time. These days, there's obviously a million more options. My recollection is that there wasn't much else around back then that had 100 presets, sounded as good, and was relatively affordable. There were the Boss ME 5 and ME 10 (yuck, in my opinion), the ADA (nice, but the one I had didn't have enough gain), plus there was some very expensive stuff from Soldana and Mesa Boogie, but I think they only had a few channels. After several years of doing gigs (just covers. LOL), one sound guy suggested DI-ing the JMP1 straight into the desk. I was dubious, because, well you know, there's no mic'ing my expensive speaker box, and "will it sounds as good as the sound I 'crafted' in my bedroom for years?', Ha ha. :-) However, DI-ing it sounded pretty good and I kept doing it every gig after that. The main benefit of this is that it's flat level, so you can fark around with your stage volume without the sound guy knowing, unless you blast everyone else out of the room. :-) Also, with no mic on your speaker, you can also move it if you need to. For all I know, there are a thousand other products now that do the same thing, and possibly better, but, ah well.... I used mine heavily for about ten years before it had any real problems, which was the power cutting in and out, which turned out to be dry joints, mostly around the transformer. Then I had to get the volume pot replaced. The buttons started playing up after about 6 or 7 years, but I still haven't got them replaced. One very minor cathc with them these is trying to find a midi footswitch.
Back in 1995 when I got my JMP-1 and 8008 amp, in Jan' 1996 I added the Rolls MIDI Buddy pedalboard which works well, although does not have any attached volume or expression pedals. Very reliable preamp and setup as a whole, although I took it to a bass player friend's place and plugged my setup into his bass cab..... Seconds later dead Marshall 8008 power amp, which had blown the protection circuits and required repair under guarantee. The repair guy was asking questions to try work out how it could have failed like it had, and I was just acting all innocent lol. Despite all this and 26 years later, the same setup works like a champ and has done plenty of gigs, studio etc.
@@EgoShredder That reminds me: I used an old Marshall 8004 Valvestate Poweramp for a while (the black one; one-rack-space) until it blew one night when I was unplugging it and the end of the speaker lead shorted on my steel speaker cover. It even started smoking! For something I thought would be a simple problem, it was a relatively expensive repair of well over 200 bucks. I initially kept the 8004 poweramp in my car as a spare, and didn't use it for several years. I can't remember why I tried it the first night (maybe at a rehearsal when I was too lazy to lug my 100w Marshall head), but I did, and it was much better than I thought, so I used it for many, many gigs. I thought I'd miss not have eq knobs on an amp, but I didn't. How interesting! Ha ha :-)
@@JordyJayHomer I have everything inside a 4U rack box which weighs an absolute TON, due all the solid wood construction and metal etc. Yeah apart from my faux pas with the bass cab, I was pretty careful and slowly switched things off before unplugging. Maybe you were in a busy environment and distracted? I've seen audience members drunk in a crowd, stumble and bring P.A. monitors crashing down in clubs etc. Always have to have your wits about you in live situations, including where they are light fingered people around.
@@EgoShredder Ha ha, yes, I was definitely packing up in hurry in a busy pub full of drunk people that night when I quickly pulled the speaker lead out of the speaker and it flung around and sparked on the steel mesh. You mentioning the weight just reminded me that that's why I put the 8004 poweramp in my car in the first place. I've got a 3-space rack, in which I had the 8004 as a spare for a couple of years without using it! Stupid. The rack also had the JMP1 and an effects unit (looped with the JMP1), so it weighed an absolute ton! :-) Ah, those were the days. LOL. Man, I forgot how heavy those little Valvestates are.
@@JordyJayHomer I'm out of condition physically these days since 2015, and when I try to lift things I lugged up flights of stairs back in the 90s, I suddenly realise how feeble I am now lol. Lockdown and online work not helped either. Anyone got a time machine they can lend us!
Awesome! Wow that's the best JMP-1 demo on line!. Thanks for filling my request. I loved that you showed it in a recording. Can you tell me the settings for OD 1 and 2 with vol, gain and pres included? The info on the EQ and tone stack was something I did not know. Changes the way you look at it. Definitely sounded best with the DSL to my ear. Dave Murray runs his into a DSL. Thanks again!
Awesome! Add a Dimarzio Super Distortion and a Tube Screamer and you've got essentially an Adrian Smith rig. And regarding that treble down, presence up, I think Lemmy used to do this with his Marshalls.
NEED SOME GUIDENCE. Just got myself a jmp 1 second hand after watching this video and ive got a few questions regarding settings, midi etc. Id love it if you would do a midi setup /impediance tutotial. How does the midi routing work with an additional fx unit? Anyhow, id like to know hope to set the impediance with 1. Straight to pa / interface (speak. Outs.) 2. Combo amp (randall se 100 w. Wich is a Stereo amp, does that change the setting, cabling? ) 3. A 100 w head / 50w head. Can i use my podxt as a midi controller? The randall fott controller perhaps? Really appriciate all help:)
Don't know about the rest but I don't think you can use podxt to control it since that pods midi implementation is very limited (you cannot customize midi messages per patch)
First thing, I love your demos. You're a great guitar player and your demos are very informative. I used to use rack pre amps like this. I've considered getting another one just for nostalgic reasons mainly I suppose. Would you recommend this one over say a mesa triaxis or an ada mp1? I'm leaning towards the jmp.
They're all very different. I have all 3 and prefer the Triaxis overall, but it can't do the 80s thing like the MP-1 or the straight up rock crunch quite like the JMP-1. The yellow c+ nice on the Triaxis is insanely good for heavy stuff and liquid leads.
i have one also but i dont have axe fx staff and i wonder if ax fx stuff can replace it ? i also watched your video which you A/B them both in a fantastic way... soundwise yes they are close but dynamically can an axe fx replace for a jmp 1 if we are interested only marshall kind of sounds.... with my regards
Great video like all your videos really enjoying I just bought one of these jmp-1 preamp I haven't gotten it yet but it should be here next week how would I run it to my Peavey classic 50 since I don't have a a power amp thanks brother keep on jamming I'll keep on watching
Once Again.. You are the best at dialing in Tones on anything Marshall !!!! I never really understood the concept of what a Pre Amp is really for when you can pretty much doo all that stuff with a Marshall DSL Head anyway?
Great video. Would running one of these into a SS power amp and then a small cab yield better results for home/small gig volume levels than (for example) a 40w all valve combo? Am I right in thinking it's essentially going to sound the same at any volume? I'm debating whether to put a small rack based rig together or get the new DSL40CR.
hair metal freak Giando Def Leppard used this (both Phil and Viv) for years live with Palmer speaker simulator units. The signal from the Palmers went to front of house, and the signal they got from Randall power amps went to onstage cabinets. So, if you go back and watch some Def Leppard live videos from the early 90s to just around last year (they switched to Fractal), you’ll get a decent idea.
Hey Leon,you are one great guitarrist ,and i have one great equipament ,the two guitar and Marshall,The Les Paul Custom and the strat,great guitar and the Marchall i have one great and wonderful sound congratulations from Argentina
Had a JMP-1 for about 10 years. Played it with a Marshall JFX-1 effects units and a Marshall 8080 power amp into a 1978 Marshall 4x12 with black back Rola G12H30 speakers. Overall I liked but I never really loved it or bonded with it. I ended up selling the rack gear and went back to a JCM800 2204. Versatile, yes... but it always had this sterility that I couldn't shake even with primo tubes that are really just there to warm things up. LOTS of op amps in that preamp just like the JCM900 (which I also do not like). I liked it much better than the ADA MP-1 but that's a bit of a backhanded compliment.
JCM800 is not a specific amp that you can say "it sounds like a JCM800". Its a line of amps that sounds very different. What does that come from referring to JCM800 for a specifik sound? A lot of people do that. What amp are they talking about?
Generally they mean 2203/2204. The 2205/2210 is hotter but still retain that same basic Marshall sound. Very few refer to the solid state line of 800's. You are correct that there are dozens of amps in the jcm800 family.
@@johanhansson4574 The 2203 did exist in the JMP line for a few years before it was rebadged as the JCM800. The JCM800 version of the 2203 sold a lot better than the JMP did and the 800 badge was very prominent. So people associate that 2203 sound with the JCM800 name.
@@brpadington A lot of rock from the late 70s was done on the JMP 2203 and almost all early metal on it with a tube screamer. I think youre wrong. I seen far more JMP than JCM here in sweden at least.
@@johanhansson4574 I am from the US. The JMP's were far more common in Europe. Marshall had a bad distribution deal with Park in the states that made them lose a lot of money. The JCM800 was the first line that Marshall sold themselves here in the states. In Europe the JMP's were very common.
Leon, I Have tried the same setup, running JMP-1 master out to Marshall JCM2000 DSL50 Return FX loop, and didn't work for me. The two master volumes of either one were not engaged and had no effect on the volumes if it's zero or all the way up. I have changed the impedance up down from both JMP-1 and the JCM2000 with no luck. Am i missing something , is my amp has a faulty FX loop ?
I've asked two couple owners of JCM2000 50 and they say the same thing. Are you sure your volumes are working when connecting to the fx loop. It feels like the power is driven at full power in this case @@LeonTodd
@@bouadie2007 I re-read your question and I understand what you meant now. The JCM2000 master volumes won't effect the fx loop input, so you need to adjust the volume of everything from the JMP-1 in that case.
Thanks! Wow that means a power attenuation is needed at this point. you have your JMP-1 cranked output and the JCM2000 working at it's full capacity, that's very loud :) Iron Maiden are using it live that way th-cam.com/video/V_5u-Br1RSA/w-d-xo.html @@LeonTodd
I had a JCM 800 4010 combo vertical inputs 82 and sold it 2 months ago. I regretted the next day that i sold it . But love watching your videos and bought a JCM 2000 DSL 50 after with the JCM 2000 Marshall 2x12 cabinet. The amp is awsome . Your excellent videos of the DSL 50 led me to it. It's a very different amp. There is a JMP-1 for sale on Ebay and was wondering would that give me the same JCM 800 tone i had on my previous amp. It sounds from your video that it would. Then i would have all different Marshall tones. Or just stick with the DSL?
Hey Leon! How is it going mate? Do you still have the Marshall JMP-1? I was wondering if you could do a comparison video between the real deal vs amplitube simulation of this preamp, through the same IR please. I'm really to find the differences between those 2. Cheers mate, keep the great job!
I had one the full on drive tones were great but the cleans we're lifeless and the mild crunchy tones were horrible, pain in the arse as a live rig, got a tsl 100 it wipes the floor with it.
AFAIK the JMP-1 uses a fixed tonestack with a 4 band graphic EQ to get around the difficulties with midi programmable EQ's, whereas the DSL features a true adjustable tone stack. The JMP-1 has diode clipping whereas the DSL does not.
Great vid ! If I understand right this video was the jmp-1 straight into your pc ? I have an old ass Hughes&Kettner Tubeman Plus rack preamp (also sounds pretty decent) but I might get a JMP-1 for a decent price. It will be solely going straight into my PC, or into a Crate VTX200S solid state amp.
@@LeonTodd Turns out I feel like there is so little gain on my JMP-1, I'm wondering if it's defective. Or maybe it only shines when run thru a true poweramp ? I also got a Rocktron Chameleon in the meantime and I like the Rocktron way better. I'm confused :) My JMP-1 is up for sale in the classifieds but I might whip it out and give it another chance.
How do you compare de jmp-1 vs the marshall dsl, im hesitating between to pick a jmp1 or a dls 40 watts combo who sounds very classy marshall style. kind regards!
yes i did it, i am impressed by the new marshall dsl 40cr im hesitating between this new marshall beast and the jmp1 that i have avaliable quite cheap. regards
As always with a preamp you need a good power amp to let it shine. I have the Mesa Simulclass 2:90 power amp and it sounds utterly stunning with the JMP-1. A lousy power amp will kill the JMP-1. Same with the Triaxis...it doesn't matter how good the pre is the power amp must be good also. Hope this helps.
You cannot do much wrong with this preamp. As iconic as a JTM45 or 1959 for me. Add a cab IR behind and you do not even necessarily need a power amp. If I use one, I like it most with a pair of KT77's. Has someting unique, but hard to describe.
Wish I had never sold my JMP-1 yrs ago. I missed it too much even though I own the Mighty Triaxis. I bought it again recently and nothing puts a smile on my face as the Marshall Crunch which the Triaxis cannot do. Btw I liked your approach to making this video so much I subbed. Great friendly video.
Yes. I have the Simulclass 2:90 power amp also and are wondering if I can run both the Triaxis and JMP-1 with a single 2/12 cab. I am not yet familiar with my rig as I got it only recently for £1500 inc-High End 6U flight Case Aluminum and plywood, Furman PL Plus CE power conditioner with LED lit front and Back Triaxis Mesa 2:90 poweramp all in out of the box condition and free delivery. The Triaxis is V2 but I do not have the manuals for either. If you can let me know how to connect up two preamps to the 2:90 then that would be very helpful:))
Yes, but maybe looking at Phil Collen’s tone, and maybe Leppard tones from Pyromania and High n Dry. Also like you did with the ADA maybe a Paul Gilbert type of tone. Dokken, Dio, Loudness........ect......Thanks
Hey, Great vid!.What did you mean at the start of the vid about the marshall head and jmp1 talking to each other and having the correct impedance? I have a jmp1 that i use with evh 5150 III lbx head and you have got me wondering if I am doing it right.I trust you are talking about going into the marshall heads return on the fx loop.I notice you have the Jmp-1 output level turned right up.Are you running it all into a cab and mic'd it up just out of curiosity?
Into a head, cab and mic'd up. Basically I just made sure the Marshall fx loop was set to +4dB (same as the JMP-1 output) to avoid any unwanted clipping.
I have used the jmp-1for about 20 yrs! I absolutely love it and if you spend time to tweak your sound to your style you will absolutely gel with it and not ever want to play any other amp!
👍🇬🇧❤JMP -1 ...BEST PRE-AMP EVER !!!!!!
ATTENTION MARSHALL!! PLEASE UPDATE AND RE-ISSUE THIS PRODUCT!!😊
I've had the Jmp1 for many years and it's a killer classic Marshall tone. Good speaker simulation for direct recording. Works well with a tube power amp or in a tube amp effects loop. I recommend it if you are a fan of the sound of the 90's
Been direct with a JMP-1 since 2006, before that, used one with two 1978 heads, that Phil Wells from Marshall "modded" for me. £8 (back in 2002!) where the mod is for them to add a power amp input to the heads. Running one of my JMP-1's L+R Master Outs into each head then into two 4x12's was totally it for me for years... when I went solo, I simply just plugged the JMP-1 direct into the mixing desk. played on stages in front of thousands using nothing more than a stock JMP-1 direct to desk. Marshall really nailed the speaker simulator and just got it right with this thing. They had to discontinue the JMP-1 due to the changes in EU solder laws (switched from lead based to water based) and that would have meant completely updating their solder baths, and all the manufacturing process, so they stopped making it. Such a huge shame. You can pick them up cheap on eBay for a song right now. AxeFX, Kemper, tried them both, kept coming back to OD1 on the JMP-1. Nothing quite beats it in a live setting. In the studio I still use Amplitube 3 and 4, but more recently I am using a JMP-1 again. Marshall should bring out a JMP-2, with USB and an onboard tuner, and effects. The CODE was absolute rubbish sadly, and for those of us who can't lug about a huge transformer laden valve amp and cab anymore, this really is a good alternative.
Despite owning numerous JMP-1's, my main one, I've had since 1997! used it every day, never went wrong, never crapped out on me. If you know how to use them (Like with any gear I guess) you can get some of the best tones around.
JMP-2 - now that would be interesting if done well!
I've been looking at a JMP-1 since they aren't too expensive on Reverb and I'm a big Iron Maiden (and Def Leppard as well, although I didn't know they used these too until recently). It seems like it would be fun to have next to my ADA MP-2 that I bought new 25+ years ago. Right now, it seems the only folks really using rack gear are large touring bands, so unfortunately I don't think Marshall would think there is enough of a market for a JMP-2, although I agree I would consider one.
Great demo and playing - this is on my hit list . My back will love you .
Classic Marshall sound, all valve / tube, and easily modernized with an additional distortion pedal - I use the Tim Pierce overdrive. Lovely how far you can get into what Dave Friedman achieved when modernizing the Marshall sound. Cheers from Germany!
Thank you a million times. Nobody has done an in-depth look at this thing, and I’ve been interested in them ever since I discovered that Def Leppard have used them live forever (they only very recently switched to all Fractal live rigs). Every time I saw Leppard, both Phil and Viv were playing these, and the sound they got with them was always perfection to me. Marshall should have kept making this.
This Preamp was used on Marilyn Manson's album Antichrist Superstar and on the following tour.
Props for the "them bones" reference! :)
I used the JMP-1 with a Bradshaw Switcher. Eventide H3000, Lexicon PCM 81, 2 SDE 3000’s, Pro VLA compressor & a Marshall 9200 or the EL 34 100/100. Compared to all my plexi’s and the old Marshall’s I have, these preamps will make you some cash. Many have also used these. They deliver whatever you want.
Now that is a rack rig!!!
Love the Marshall JMP-1 And even more favoritley absolutely love my ADA MP-1. I actually have the settings Nuno Bettencourt used with the ADA MP-1 if anyone would like them.
Best preamp ever made!!!!!!! Can’t stop playing it!!!
I owned one of these for about 20 years with a Marshall 9200 power amp (5881 tubes). I bought them new and they served me well for a long time. It was an amazing rig. I loved the 5881 tubes. It really became fat, chunky and amazing at stage volumes in larger venues. I would get a sound somewhere between Michael Schenker and George Lynch (Tangled in the Web) just using the preamp gain and the power tube gain. The cool thing with a rig like that is that you can push the volume of the power amp separately from the preamp gain, so you can find your tone with that much more control.
Another great thing is that I could place something like a TC Electronic G Force in the line between the JMP-1 and the 9200 power amp and that was also amazing. This also gave me the option of splitting the signal into stereo out and using both sides of the 9200 power amp separately and using stereo effects. I also used a TC Electronic D Two before I got the G Force, but I don't remember if that was run the same way or actually in the effects loop. I loved and used the midi in the JMP-1, changing amp channels and effects simultaneously, although I primarily used one aggressive amp sound and used the volume on my Les Paul to adjust that sound. On a lot of my midi settings, I had it so that the amp would stay the same and the effects would change. The JMP-1 was really well designed. I wish that they kept updating this model as they went into the higher gain era. I don't know if this is correct, but as I understand it, Marshall could no longer make the JMP-1 because of something internal that new environmental regulations made illegal. Not sure what that would have been or why there would not be an alternative. The closest amp that I have found to be a successor to that rig is the JVM410HJS. Just a great amp. It had to be for me to sell my JMP-1 and 9200.
Lynch tangled in the web is a godly tone.
AnAmericanGuitarist - thanx for the detailed comment brother.
Another thing that I forgot to mention is that I placed Mesa 5881 Tubes in the 9200 and Mesa gives you the option of early, mid or late breakup tubes. I always went with mid. I would normally put my 9200 volumes around 6 or 7 and then control the volume of the whole rig via the volume knob on the JMP-1. I still miss that rig.
I still use my JMP-1 with the 9200 power amp set up to this day. Served me well since the early 90s. Great bits of kit.
Leon you do fantastic and informative videos!! This one is one of my favourites along with your mp-1 video 👍🏻 thanks for great (and honest) content
Very welcome!
Grab yourself a cup of coffee and read Leon’s comment section pertaining to the JMP-1.
Thank you good sir for your genuine enthusiasm for all things guitar and gear related.
You’ll be at 200k subs before you know it. Nobody is more deserving. This channel never ceases to impress.
Where may i find this?
My favorite I also have the ADA mp1..love both, both get the Marshall sound...
Love the strat colour.Nice to see the pickguard in vintage white ala Blackmore,leaving the pickups etc black!!!!
I bought my first one in the early 2000's and still have it. I bought a second one in case something happened to the first one. Love them.
Od 2 is great by itself, of 1 with a boost in front sounds like a 800 from the 80.
They great. I Never understood why they didn't make a head that was based off of this.
100 channel fully programmable head...would have been great too.
After I saw this video,I just bought one. It sounds fantastic. Modeling is very advanced but tube stays tube. JMP-1 -> MOOER Radar (4x12") -> Interface. Great, great sound.
Ich schwanke noch zwischen dem Two Notes Cab M und dem Mooer Radar. Mal den Cab M mit dem JMP ausprobiert ?
@@maudo2215 Nein. Bin mit dem MOOER Radar restlos glücklich. Super Teil
Prima! Danke für die Antwort. :)
@@maudo2215 :-)
I currently play a JCM-800. I am thinking about switching up to this preamp but I would love to hear a side by side comparison!!! The band has switched to in ear monitor system with each of us having our own mix and individual control of our own mixes. Lugging the amp around isn't really practical anymore.
Aaah the good ol’ JMP1! Used to have a rig consisting of the JMP1, a Digitech GSP2101, the Marshall 9200 dual monobloc and a Marshall 1960 4x12 cab set to stereo. Sweet memories!
Good lord I bet that was huge!
Leon Todd Haha, it was huge and very heavy. Drove it around in the back of my moms ‘84 Toyota Starlet. Hardly could steer it. 😂 But the sounds, though! I immediately recognized the sound! Great vid, Leon!
EMG ENT Yeah! The 2101 was basically the the first modeler and indeed, the FX (not the preamp) are still fantastic...especially the bottomless chorusses and multitap delays...
EMG ENT I think you’re right, wasn’t that a mod? Anyway, just came across a second handed 2101...120 euro...I think I’m gonna buy it and make a vid with it. :)
I wouldn't say the GSP 2101 had a bad preamp at all! In fact the Saturated tube mode is electrically very similar to the Engl e530 preamp. The best way to take full advantage of it is to make all your algorithms with the 5 band parametric eq and/or the 10 band graphic the first modules in the alg and run the unit 100% wet.
With the Les Paul, the tone is absolutely SICK!!!! Haven't tried one but I would like to.
Easily one of the best Pre-amps ever made. In my opinion it is right up there with the ADA Mp-1.
The two of them together in stereo would be insane!
Leon Todd Throw in a triaxis and do a wet dry wet setup or run the triaxis down the middle.
*Drools*
mejor marshall
Great companion to the mp-1.
Greetings from Cali, Colombia... I have the JMP1 for more than 10 years now, and i still in LOVE, it is so vesatil, intuitive, sounds GREAT, in simple words, WHY MARSHALL TAKE THIS PREAMP OUT OF PRODUCTION??? Guitarist NEEDS a real great sound and this preamp it have EVERYTHING for a great tone... My main guitar rig is, this Marshall JMP1 midi tube preamp, Peavey Tube Power Amp Classic Series 50/50, Alesis MidiVerb 4, Line 6 X2 wireless guitar system, phonic power conditioner and a Marshall Lead 1960 4x12 A cabinet and the Peavey Professional Midi Foot Control... As i already said, after more tgan 10 years with this rack, I STILL IN LOVE!!! ❤
Well THANKS for this video and for read my comment, if anyone here wants to follow me, go to my official FB FanPage, here in youtube, or at instagram as Adrian Oleas or my Band Darkempire... See you guys!!! 🤘😎🎸🇨🇴
To get an AC/DC 'Low gain' sound for instance...would one use a clean channel gained up high OR OD1 with gain on say 1 or 2 ?...OR does this unit simply not do those 'Classic' Marshall sounds ( Zep, Lizzy, Purple, AC/DC etc)
I understand this rack came out when higher gain was the rage.
I used to record EVERYTHING through a jmp-1. Bass ,vocals ,overheads and of course guitar. People used to ask me what expensive mic pres I used cause everything sounded so juicy!
Overheads? That's wild!
@@LeonTodd yup. I used battery power on some nice handheld senheiser vocal mics through the jmp-1 clean channel. Best tube pre/ eq combination for warmth with sizzle.
@@eduardwilliams1245 need to try this
@@LeonTodd I also used to run the entire mix through it in mono! Hahaha, assign it to a bus and run it up slowly until it added a little something, always checking for phase of course. You'll love Todd. Just think of it as a tube channel strip. With an optical compressor on the end it ,EVERYTHING sounds good through it.
@@LeonTodd oh yeah and to state the obvious, don't use the cab sim out if you're using it as a mic pre.
Ugh yes. JMP1
Heavenly
Got two of them, one each in my two rack systems. Great machines they are, love them very very much. Thanks for this great review, Leon!
I love this! Owned a JMP-1 for a long time. Together with my Engl 830/50 and my Kitty Hawk 4x12 loaded with G12T75 it sounds amazing.
I'd love to find some kitty hawk gear one day
Years ago I got two Kitty Hawk Cabs with 4x12 G12T75 from a friend of mine for a friendship prize. He himself had two more. Half a year ago, one broke and he asked if I wanted to give one back. What can I say? Friends will be friends. And so I sold one back for the same price.
would this be good for metal at all? or would an engl be better? I know dave mustaine used to use marshalls and stuff same with alexi laiho.
👍JMP-1 (best pre amp ever made)
Triaxis, X99, CAE 3+ and all things Fractal
there's a reason Rev. Billy has been using them for so long
@@fanoboss it's called money, not tone
fijne vent Billy gibbons has been using this preamp because Of money how?
@@rickfeith6372 ada mp1
I still have all major 3 preamps of the 80s-90s. The JMP-1, the ADA MP-1 3TM and the Triaxis. Both the ADA and the Triaxis are Beasts on sound and for Metal Chunky tones, you can't go wrong. My Triaxis is my go-to "Metallica-Boogie Thrash" rig, my ADA is my go-to "Marshall-on-steroids" Thrash rig. So for years, JMP-1 (being softer and all) just wasn't cutting it for me. HOWEVER, recently I decided to setup a "Malmsteen" rig...Since a "Plexi" is out of the question (money+volume), I used the JMP-1 with a 20/20 Marshall power amp to get a Plexi-sound and used the famed DOD250 in front. And OH-MY-GOD, it just couldn't get any better. I am amazed on how convincing the JMP-1 as a "cranked Plexi" is....Compared it with all Plexi sound samples out there, it does the job brilliantly!! And with the DOD250 in front, its heaven. Early Malmsteen sounds (Marching out-Trilogy etc.) are SO spot on, you can only tell its NOT Malmsteen by.....my playing :)
Getting some work done,on my 1984, Greco les paul guitar 550. It's Awesome! Great channel and playing
Most versatile with cleans and all Marshall sounds in one box and still popular with touring stars. Why is it discontinued? Rack units went out of fashion?
This unit had some fuckin BRILLIANT CLEAN TONES!! Fender and Roland Jazz Chorus 120 CLEAN TONE TYPES!! I owned one for near 15 years and when it finally died I was told Marshall bailed on the line pf them because of components...rather than doing a whole redo pf components they discontinued the unit.. Gainstahes were not the best but the cleans were AWESOME
@Schmoolie Deninostein Holy shoot... I knew Trent Reznor used one. CORGAN NOW? I think I'm sold. Corgan's live sound back then was pretty sweet. A little chaotic and 90's, but pretty sick. Also Iron Maiden uses them still, if I'm correct. Gotta get that cash, before they jump in price again.
Awesome cleans for sure. But I honestly think this amp's real charm is the OD channels. They have such a unique bark and growl to them that I usually only hear from really expensive amps from Germany.
Hi there. Alot of the players I like, Phil Collen, Ace Frealey Billy Gibbons tend to use this for live work. Are these preamps more for live use than as a general amp? I love the sound of this amp and would want to use it as my sole amp
It'll work for whatever you want to use it for!
@@LeonTodd That's great. Thanks for the help 😊
In 2019 i got one JMP-1 Stock. I'm just a bit worry about the backup battery soldered at 2 or 3 terminals on the pcb... Mr. Leon Todd would throw some light about this issue ?! Thanx. Cheers from Viamao City - RS BRAZIL 🇧🇷
I'm not too familiar with any of the internal specs unfortunately. Might be wrth writing to Marshall support and seeing if they can point you in the right direction.
@@LeonTodd Mr. Todd: thank you anyway! I'm glad with your answer and i'll try contact Marshall support to find some option for this situation. Leakage bateries could ruin the pcb, and make the whole device useless, if it not replaced. Love your channel and your songs!!!! Excuse for my slop english... kkkk... Cheers from Viamão City, RS Estate 🤘😃🎸🇧🇷Brazil.
Just bought one five days ago. Already trying to work out where it has been all my life! Did and album in lockdown and I really wish I had this to do the guitars with as it sounds so good!
How are you coming out of the JMP-1? I see a Two Notes device in the background. Thanks for any advice. Mine just showed up today!
Came to check this out because A.) Stephen from Deftones used/uses this preamp and B.) I wanted to see how this compares to the STL Tones Amphub version, the Brit J1. Pretty close comparison, and I think I might get a used JMP-1 for my live rig. absolutely love the way it sounds with a boost at the front in OD2!
Leon, Tremendous channel! I’m wondering your feelings on this versus an Axe-fx III (which I own)?
I’m thinking of maybe going the Synergy route or this on the front end so I can use pedals to overdrive the front, which you obviously can’t
do on the Axe. I also own a Friedman be-100 which I can’t seem to gel with as it’s a bit too stiff for me. Thanks for what you do!
I do like the JMP Pre and Brit Pre on the AX8!
Jmpre is so good for 80's tones!
You know what you are talking about, you have awesome gear and you're cool. Subscribed
Much appreciated. Any demo's you'd like to see?
Would I be asking to much if I requested a demo of the Mesa mark IIC+ ?
Thanks for the reply.
That's some most excellent tasty vibrato you have there Sir!
I have a special request: can you do a follow-up short video using this JMP-1 unit with a JB/Jazz humbuckers 25 frets guitar (not a Gibson nor a Stratocaster) to replicate Dave Mustaine's rhythm tone. I know he used the JMP-1 a lot in the past (early albums played LIVE) powered by the Marshall 9100 block amp. What I'd like to get are the JMP-1 settings you would use to replicate his tone as ''best'' as you can. I know it's kind of hard because he has always used a lot of effects/EQ ''mystery boxes'' to carve his sound, but if you could at least, give me a base setup, that would be great. Cheers!
Mi piacerebbe averlo nel rack bellissimo.
Buone feste a tutti 🎄
How is the FX loop in this preamp? Is it a "proper" FX loop, buffered, and doesn't sound like crap? :)
Leon what is meant by line level you mention at the start. I have this gear and want to rig it up , presume you mean both the switches are matching so -10db or +4
Thanks
I bought mine from George Lynch, and am in the process of cataloguing his presets, want a link when I'm done?
yes
Dude! I can’t wait to here!
take pictures of the tubes used and mods if any!
Great video. I dig your playing and presentations.
I had one of these along w a Roland RSP-550 back in the ‘90s. Played it through a Boogie Mark IIB combo. Sounded great but wish I’d tried it through a EL34 power amp back then after hearing this video.
I’m thinking of getting another (which is how I landed here). It’ll be mainly for recording and I’m wondering how the DI and speaker simulators sound. I’ve got the OX Amp Top Box; too but all my amps are 6L6 still. So NOW what...!!?? 🤔
The DI sounds pretty dated IMO
Yeah. Friend of mine warned me off a half hour ago. That was one point. It’s a big one considering why I want it. Thanks.
Get an Atomic Amplifire for a little bit more money - sounds way better direct. Or pony up some extra cash and get a Fractal AX8 or FM3, the JMP1 models in them are dead on.
Cuppa coffee and gear talk. Great way to start the day!
Right now I’m using an XTS Atomic Overdrive for the Marshall sound. Excellent for the JCM800 sound and more. I like their stuff.
I’m new to recording electric. Everything before was solo acoustic, which is pretty simple compared. Interesting you’d mention the Fractal stuff. I checked out your vids on Kemper and/or Fractal. Friend of mine picked up the Kemper rack after checking them out, too. Monster engine.
I ended up getting that UA OX. I’m pretty attached to my pedals and amps, as is. But so far I’m not getting my gear to translate well through it to my DAW. Especially the distortion stuff. I’m giving it a little more time but might do an exchange.
I was considering the JMP-1 through the OX but see above. I’ll check out the Amplifire. Thanks for the tip.
Btw: I really did love that JMP-1 in the ‘90s except for one very big thing: latency. Three man band with lots of patch changes...that split second of silence drove me bonkers.
So cool that you reply, Leon. Good day to ya!
11:40 Where Eagles Dare 🤘
So glad someone noticed! My favourite Maiden tune :D
Kinda hard not to notice a song by your favorite band ;) They are also the reason why I'm watching videos about Marshall JMP-1.
I really like mine. Ya gotta remember that when they came out in the early '90s, they were pretty "big" for the time. These days, there's obviously a million more options. My recollection is that there wasn't much else around back then that had 100 presets, sounded as good, and was relatively affordable. There were the Boss ME 5 and ME 10 (yuck, in my opinion), the ADA (nice, but the one I had didn't have enough gain), plus there was some very expensive stuff from Soldana and Mesa Boogie, but I think they only had a few channels.
After several years of doing gigs (just covers. LOL), one sound guy suggested DI-ing the JMP1 straight into the desk. I was dubious, because, well you know, there's no mic'ing my expensive speaker box, and "will it sounds as good as the sound I 'crafted' in my bedroom for years?', Ha ha. :-) However, DI-ing it sounded pretty good and I kept doing it every gig after that. The main benefit of this is that it's flat level, so you can fark around with your stage volume without the sound guy knowing, unless you blast everyone else out of the room. :-) Also, with no mic on your speaker, you can also move it if you need to. For all I know, there are a thousand other products now that do the same thing, and possibly better, but, ah well....
I used mine heavily for about ten years before it had any real problems, which was the power cutting in and out, which turned out to be dry joints, mostly around the transformer. Then I had to get the volume pot replaced. The buttons started playing up after about 6 or 7 years, but I still haven't got them replaced. One very minor cathc with them these is trying to find a midi footswitch.
Back in 1995 when I got my JMP-1 and 8008 amp, in Jan' 1996 I added the Rolls MIDI Buddy pedalboard which works well, although does not have any attached volume or expression pedals. Very reliable preamp and setup as a whole, although I took it to a bass player friend's place and plugged my setup into his bass cab..... Seconds later dead Marshall 8008 power amp, which had blown the protection circuits and required repair under guarantee. The repair guy was asking questions to try work out how it could have failed like it had, and I was just acting all innocent lol. Despite all this and 26 years later, the same setup works like a champ and has done plenty of gigs, studio etc.
@@EgoShredder That reminds me: I used an old Marshall 8004 Valvestate Poweramp for a while (the black one; one-rack-space) until it blew one night when I was unplugging it and the end of the speaker lead shorted on my steel speaker cover. It even started smoking! For something I thought would be a simple problem, it was a relatively expensive repair of well over 200 bucks.
I initially kept the 8004 poweramp in my car as a spare, and didn't use it for several years. I can't remember why I tried it the first night (maybe at a rehearsal when I was too lazy to lug my 100w Marshall head), but I did, and it was much better than I thought, so I used it for many, many gigs. I thought I'd miss not have eq knobs on an amp, but I didn't. How interesting! Ha ha :-)
@@JordyJayHomer I have everything inside a 4U rack box which weighs an absolute TON, due all the solid wood construction and metal etc. Yeah apart from my faux pas with the bass cab, I was pretty careful and slowly switched things off before unplugging. Maybe you were in a busy environment and distracted? I've seen audience members drunk in a crowd, stumble and bring P.A. monitors crashing down in clubs etc. Always have to have your wits about you in live situations, including where they are light fingered people around.
@@EgoShredder Ha ha, yes, I was definitely packing up in hurry in a busy pub full of drunk people that night when I quickly pulled the speaker lead out of the speaker and it flung around and sparked on the steel mesh. You mentioning the weight just reminded me that that's why I put the 8004 poweramp in my car in the first place. I've got a 3-space rack, in which I had the 8004 as a spare for a couple of years without using it! Stupid. The rack also had the JMP1 and an effects unit (looped with the JMP1), so it weighed an absolute ton! :-) Ah, those were the days. LOL. Man, I forgot how heavy those little Valvestates are.
@@JordyJayHomer I'm out of condition physically these days since 2015, and when I try to lift things I lugged up flights of stairs back in the 90s, I suddenly realise how feeble I am now lol. Lockdown and online work not helped either. Anyone got a time machine they can lend us!
Is there a video that goes over the midi mapping feature?
Hi. I just got the jmp-1 and want to hook up with my sv20 for the power section .could you tell me how Do I hook it up ? Thx
Awesome! Wow that's the best JMP-1 demo on line!. Thanks for filling my request. I loved that you showed it in a recording. Can you tell me the settings for OD 1 and 2 with vol, gain and pres included? The info on the EQ and tone stack was something I did not know. Changes the way you look at it. Definitely sounded best with the DSL to my ear. Dave Murray runs his into a DSL. Thanks again!
Rob Miller my pleasure, thanks for the suggestion. From memory OD1 B/M/T/P 0/-1/1/0, OD2 0/-2-1/2
That's the best u Eva herd a DSL sound :)
Awesome! Add a Dimarzio Super Distortion and a Tube Screamer and you've got essentially an Adrian Smith rig.
And regarding that treble down, presence up, I think Lemmy used to do this with his Marshalls.
NEED SOME GUIDENCE. Just got myself a jmp 1 second hand after watching this video and ive got a few questions regarding settings, midi etc. Id love it if you would do a midi setup /impediance tutotial.
How does the midi routing work with an additional fx unit?
Anyhow, id like to know hope to set the impediance with
1. Straight to pa / interface (speak. Outs.)
2. Combo amp (randall se 100 w. Wich is a Stereo amp, does that change the setting, cabling? )
3. A 100 w head / 50w head.
Can i use my podxt as a midi controller? The randall fott controller perhaps?
Really appriciate all help:)
Don't know about the rest but I don't think you can use podxt to control it since that pods midi implementation is very limited (you cannot customize midi messages per patch)
First thing, I love your demos. You're a great guitar player and your demos are very informative. I used to use rack pre amps like this. I've considered getting another one just for nostalgic reasons mainly I suppose. Would you recommend this one over say a mesa triaxis or an ada mp1? I'm leaning towards the jmp.
They're all very different. I have all 3 and prefer the Triaxis overall, but it can't do the 80s thing like the MP-1 or the straight up rock crunch quite like the JMP-1. The yellow c+ nice on the Triaxis is insanely good for heavy stuff and liquid leads.
Hello Leon , i would like very much that you make a video with MXR ZW-44 + JMP-1
i have one also but i dont have axe fx staff and i wonder if ax fx stuff can replace it ? i also watched your video which you A/B them both in a fantastic way... soundwise yes they are close but dynamically can an axe fx replace for a jmp 1 if we are interested only marshall kind of sounds.... with my regards
In short, yes

Great video like all your videos really enjoying I just bought one of these jmp-1 preamp I haven't gotten it yet but it should be here next week how would I run it to my Peavey classic 50 since I don't have a a power amp thanks brother keep on jamming I'll keep on watching
Once Again.. You are the best at dialing in Tones on anything Marshall !!!! I never really understood the concept of what a Pre Amp is really for when you can pretty much doo all that stuff with a Marshall DSL Head anyway?
My JMP-1 just crapped out on me. Started by just sounding very muffled and raspy, and now I can barely get a sound out of it. Any ideas on what to do?
Busted tube? Bad caps? Worth taking to a tech.
@@LeonTodd Weird thing, just tried it out through the headphone jack, sounded fine.
@@OlleForsberg try some contact cleaner on the outputs in that case!
Great video. Would running one of these into a SS power amp and then a small cab yield better results for home/small gig volume levels than (for example) a 40w all valve combo? Am I right in thinking it's essentially going to sound the same at any volume? I'm debating whether to put a small rack based rig together or get the new DSL40CR.
tube preamp is where its at IMO.
try something like the seymour duncan twin tube into a decent clean channel
If i am going direct to p.a. where can i put my amp sim pedal and (time based effects ) in signal chain
How would it sound in a solid state guitar power amp like Palmer or something similar?
hair metal freak Giando Def Leppard used this (both Phil and Viv) for years live with Palmer speaker simulator units. The signal from the Palmers went to front of house, and the signal they got from Randall power amps went to onstage cabinets. So, if you go back and watch some Def Leppard live videos from the early 90s to just around last year (they switched to Fractal), you’ll get a decent idea.
Hey Leon,you are one great guitarrist ,and i have one great equipament ,the two guitar and Marshall,The Les Paul Custom and the strat,great guitar and the Marchall i have one great and wonderful sound congratulations from Argentina
Hi Leon :) do you think this JMP-1 is better sound than marshall 2210 drive? thanks a lot
Nice sound in the riff that starts from min 11:15 to min 11:40 ....yeahhh !!
Had a JMP-1 for about 10 years. Played it with a Marshall JFX-1 effects units and a Marshall 8080 power amp into a 1978 Marshall 4x12 with black back Rola G12H30 speakers. Overall I liked but I never really loved it or bonded with it. I ended up selling the rack gear and went back to a JCM800 2204. Versatile, yes... but it always had this sterility that I couldn't shake even with primo tubes that are really just there to warm things up. LOTS of op amps in that preamp just like the JCM900 (which I also do not like). I liked it much better than the ADA MP-1 but that's a bit of a backhanded compliment.
I ended up moving from a JMP1 based rack to a DSL50 and never looked back.
Great demonstration
Thanks so much for watching
JCM800 is not a specific amp that you can say "it sounds like a JCM800". Its a line of amps that sounds very different. What does that come from referring to JCM800 for a specifik sound? A lot of people do that. What amp are they talking about?
Generally they mean 2203/2204. The 2205/2210 is hotter but still retain that same basic Marshall sound. Very few refer to the solid state line of 800's. You are correct that there are dozens of amps in the jcm800 family.
@@brpadington The 2203 was in production in the JMP line for many years before the JCM800 so I just dont get it.
@@johanhansson4574 The 2203 did exist in the JMP line for a few years before it was rebadged as the JCM800. The JCM800 version of the 2203 sold a lot better than the JMP did and the 800 badge was very prominent. So people associate that 2203 sound with the JCM800 name.
@@brpadington A lot of rock from the late 70s was done on the JMP 2203 and almost all early metal on it with a tube screamer. I think youre wrong. I seen far more JMP than JCM here in sweden at least.
@@johanhansson4574 I am from the US. The JMP's were far more common in Europe. Marshall had a bad distribution deal with Park in the states that made them lose a lot of money. The JCM800 was the first line that Marshall sold themselves here in the states. In Europe the JMP's were very common.
Can hear strings above the nut ringing out. I think.
Leon,
I Have tried the same setup, running JMP-1 master out to Marshall JCM2000 DSL50 Return FX loop, and didn't work for me. The two master volumes of either one were not engaged and had no effect on the volumes if it's zero or all the way up. I have changed the impedance up down from both JMP-1 and the JCM2000 with no luck. Am i missing something , is my amp has a faulty FX loop ?
Very strange. Worth getting it looked at by a tech.
I've asked two couple owners of JCM2000 50 and they say the same thing. Are you sure your volumes are working when connecting to the fx loop. It feels like the power is driven at full power in this case
@@LeonTodd
@@bouadie2007 I re-read your question and I understand what you meant now. The JCM2000 master volumes won't effect the fx loop input, so you need to adjust the volume of everything from the JMP-1 in that case.
Thanks! Wow that means a power attenuation is needed at this point. you have your JMP-1 cranked output and the JCM2000 working at it's full capacity, that's very loud :) Iron Maiden are using it live that way

GRECO!!!!
I had a JCM 800 4010 combo vertical inputs 82 and sold it 2 months ago. I regretted the next day that i sold it . But love watching your videos and bought a JCM 2000 DSL 50 after with the JCM 2000 Marshall 2x12 cabinet. The amp is awsome . Your excellent videos of the DSL 50 led me to it. It's a very different amp. There is a JMP-1 for sale on Ebay and was wondering would that give me the same JCM 800 tone i had on my previous amp. It sounds from your video that it would. Then i would have all different Marshall tones. Or just stick with the DSL?
i just posted a DSL vs 800 comparison which might answer a few questions ;)
Your a good man! Doing a great job. Thanks for the reply!
Hey Leon! How is it going mate? Do you still have the Marshall JMP-1? I was wondering if you could do a comparison video between the real deal vs amplitube simulation of this preamp, through the same IR please. I'm really to find the differences between those 2. Cheers mate, keep the great job!
Nice demo, i still miss my jpm!!
any idea where i can pick up one of these bad boys? this thing is absolutely amazing
At this stage eBay is probably the best bet, although prices are creeping up past the $800AUD mark which I'd find hard to justify.
What does it sound like without the tubes in?
I had one the full on drive tones were great but the cleans we're lifeless and the mild crunchy tones were horrible, pain in the arse as a live rig, got a tsl 100 it wipes the floor with it.
I moved from this to a DSL and never looked back ;)
Leon Todd yes another great sounding Marshall I now have a jvm 100h fantastic!
Greco! Such good stuff to be had from them!
Hey Leon, I got this JMP-1 pre-amp. In your opinion is it a keeper? Tossing up whether to sell it to help fund an AXE-FX
Depends on what they're selling for used I guess. The Axe JMP-1 is bang on and you've got a universe of other tones in there too.
I know it’s been a few years since you posted this, how does it sound into the DSL vs into the Mesa rack power amp?
Great video! What do you think is the differences between the preamp in the JCM2000 and the JMP-1 preamp?? Greeting from Sweden :-)
AFAIK the JMP-1 uses a fixed tonestack with a 4 band graphic EQ to get around the difficulties with midi programmable EQ's, whereas the DSL features a true adjustable tone stack. The JMP-1 has diode clipping whereas the DSL does not.
Thanks for the reply! If you compare the two sound wise . What are the differences? Thanks!@@LeonTodd
Great vid ! If I understand right this video was the jmp-1 straight into your pc ?
I have an old ass Hughes&Kettner Tubeman Plus rack preamp (also sounds pretty decent) but I might get a JMP-1 for a decent price. It will be solely going straight into my PC, or into a Crate VTX200S solid state amp.
I ran it into the fx return of my Marshall DSL
@@LeonTodd Turns out I feel like there is so little gain on my JMP-1, I'm wondering if it's defective. Or maybe it only shines when run thru a true poweramp ? I also got a Rocktron Chameleon in the meantime and I like the Rocktron way better. I'm confused :) My JMP-1 is up for sale in the classifieds but I might whip it out and give it another chance.
How do you compare de jmp-1 vs the marshall dsl, im hesitating between to pick a jmp1 or a dls 40 watts combo who sounds very classy marshall style. kind regards!
I've got demo's of all those on my channel, have a listen and see if it helps :)
yes i did it, i am impressed by the new marshall dsl 40cr im hesitating between this new marshall beast and the jmp1 that i have avaliable quite cheap. regards
As always with a preamp you need a good power amp to let it shine. I have the Mesa Simulclass 2:90 power amp and it sounds utterly stunning with the JMP-1. A lousy power amp will kill the JMP-1. Same with the Triaxis...it doesn't matter how good the pre is the power amp must be good also. Hope this helps.
You cannot do much wrong with this preamp. As iconic as a JTM45 or 1959 for me.
Add a cab IR behind and you do not even necessarily need a power amp. If I use one, I like it most with a pair of KT77's. Has someting unique, but hard to describe.
Wish I had never sold my JMP-1 yrs ago. I missed it too much even though I own the Mighty Triaxis. I bought it again recently and nothing puts a smile on my face as the Marshall Crunch which the Triaxis cannot do.
Btw I liked your approach to making this video so much I subbed. Great friendly video.
Cheers for the Sub! A rack with a JMP-1 and Triaxis would just about do it all.
Yes. I have the Simulclass 2:90 power amp also and are wondering if I can run both the Triaxis and JMP-1 with a single 2/12 cab. I am not yet familiar with my rig as I got it only recently for £1500 inc-High End 6U flight Case Aluminum and plywood, Furman PL Plus CE power conditioner with LED lit front and Back Triaxis Mesa 2:90 poweramp all in out of the box condition and free delivery. The Triaxis is V2 but I do not have the manuals for either. If you can let me know how to connect up two preamps to the 2:90 then that would be very helpful:))
Both Billy and Dusty from ZZ Top have used these since they were first available.
great demo brother
Can you do a video like the ADA 80’s tones, but with the JMP1? Thanks
Sounds fun; you thinking Leppard/Maiden tones?
Yes, but maybe looking at Phil Collen’s tone, and maybe Leppard tones from Pyromania and High n Dry. Also like you did with the ADA maybe a Paul Gilbert type of tone. Dokken, Dio, Loudness........ect......Thanks
Marcel Coenen had the best lead tone I've ever heard using this preamp. Checkout his song Moyra.
Ok cool could I run the jmp1 into the fx return on my Joyo zombie amp?
Should work a treat
Exactly how do I do this if you don't mind explaining it to me rack gear new to me.
Hey !!
Can you plug directly into a cabinet , say an Orange 2 x 12
You'll need to connect it to a power amp
Hey, Great vid!.What did you mean at the start of the vid about the marshall head and jmp1 talking to each other and having the correct impedance? I have a jmp1 that i use with evh 5150 III lbx head and you have got me wondering if I am doing it right.I trust you are talking about going into the marshall heads return on the fx loop.I notice you have the Jmp-1 output level turned right up.Are you running it all into a cab and mic'd it up just out of curiosity?
Into a head, cab and mic'd up. Basically I just made sure the Marshall fx loop was set to +4dB (same as the JMP-1 output) to avoid any unwanted clipping.
Cool!,Thanks Leon.Love your work man,Killer playing too.
