This is what a lot of Splawns and Friedmans are going for and it was in this amp all along 🤘🏼
Some guy tried selling me one of these for $300. I turned him down because I didn’t know anything about it and was already buying a jcm2000 from him that day. Man I regret that now.
Couldnt go wrong with a jcm 2000,you still win.Dont worry
Those things are pretty fun. The Mk. III and SL-X are super similar in that both have the gain sensitivity knob which essentially controls a boost in front of the preamp; the difference being that the Mk. III's boost section is solid state and has some clipping diodes in it, while the SL-X uses a tube instead.
900 slx and 900 mkiii both sleepers and great amps ... love them
Dude…legitimately this amp is ticking all the boxes for me! Absolutely loving it, and good god does it blend nicely with that Mesa I just got too. Ultimate high gain Marshall tone!
Awesome man! I'm happy you're digging it! Definitely one of the best high gain Marshalls!
Cool video! I have one of these, bought it for about $600-650 a couple of years ago. Currently using it in my death/thrash band, with a Maxon OD808 in front of it for a little extra clarity. We're playing in C standard, and it works great for that type of music. It's a bit muddy at lower volumes, but it clears up a lot when you crank it (I usually just use the A channel, with the volume up at about 6-7). Cheers from Sweden.
Man, I am always looking forward to these videos, and they never disappoint! Keep them coming!
I just got an SL-X with EL-34s not too long ago and I was searching your channel to see if you had anymore videos beyond that Q&A. Dreams do come true, thanks man.
It was fate!
The SLX-900 & MK-III 900's were the last of the Marshalls I cared for........thanks for demoing this kick-ass dinosaur👍
I never realized the jcm900 amps sounded this good. I've always been a hardcore 800/2203/plexi guy but I can definitely see myself owning one of these beasts for some higher gain riffage. Cheers!
This one in particular is absolutey killer. Best of the bunch, IMO
Ive had my eye on this old beast used for while now, i am glad that you showed what it can do with pedals! I might have to get one now for a good price as they increased the prices on the sc20 jcm 800 heads!!
Harms way with the Dirty Tree was brutal!!! This is my dream Marshall!
I got one after watching that video and to be honest, that was a great advice.
Great amp! I had no clue it would do its thing that well. A keeper definitely.
Looking forward to more videos (comparison) with that JCM900 SLX.
I’m just happy Arnold is getting this old school monster. I always liked the particular sound of these beasts
Yes! I LOVE my SLX! I was able to buy one for cheap. It’s a keeper and no doubt will be a future classic.
As do I …. Does yours also have EL34’s??? Mine is 50 watts and I bought a Lynch mod from you and installed it in my 50 watt EL34 SL-X….. best amp I ever heard or own…
@@xvx6663 Yes, EL-34s in mine as well. I’ve not compared it with the 6L6/5881 version myself. I like it as is though :)
Great amp! Also have the 5881 version, but got it modded to take EL34s. More balls and a bit more raw/ aggressive power amp sound. Loved and played it with a SD-1 and EMG 85/ bridge in my former Hardcore band
My favorite amp. Love it.
Killer demo Kyle! I liked the lower and mid gain settings! Sounded like a good 800, with a bit more gain - just what the doctor ordered in the '80's, about 10 years too late for Marshall though!
Great review, quick, straight to the points, well done. Ive had an original red tolex 50W SLX since the 90s. Unless you need a really clean tone (which you would go for a Vox or Fender anyway) these things can dial in basically any Marshall sound. It has way more gain than I ever used and takes Delay, Chorus, Flanger pedals just fine. And all tube, no diode which I think was the main knock on the other 900s. If you want just one Marshall head to cover 70s through 90s sounds IMO this is your best choice.
I love seeing coverage of JCM 900s that aren't the Dual Reverb (the 50W Master Volume MkIII head is my ideal amp so far), enjoyed the sound of this! Loved hearing When I Come Around in there too.
And it goes to 20!... Great riffing! Probably an underrated amp. Sounds really good to me.
Thanks man! And yes, one of my favorite Marshalls out there!
This is your buddy from messengers chance. Been watching you grow brotha! Can’t wait for the 5150 iconic series as well in your latest videos
Great amp, totally underrated future classic.
Nice! I have a slx and to me its what i kinda expected a jcm800 sound 🤷 mine have been switched to el34's...killer vid as always
My SLX 100 watt sounds fantastic! Love it! A different great tube overdrive compared to my early 70's Superleads. You know how to get these amps in the tone zone Kyle. Great ears definitely. My SLX has 500 volts on the plates of the power tubes. This definitely explains why this amp can cause hearing loss quickly....it can get extremely loud! Like hear it in the next zip code loud!
dang that sounds absolutely sick.
Nice demo, thanks! I just picked up that same amp…very 800-ish in the best way. Love the Alice Cooper riff!
Yes, loved it. Glen Buxton has always been one of my favorite players. Very underrated, great sound.
I have a 50w Canadian head with EL34 power. I put a balanced 5751 in the preamp V1 to cool the gain. And a Sovtek Long plate balanced
12AX7 in the Phase inverter position. Damn fine and quiet High Gain.
Mate, great video as usual! Though, the two amps comparison videos are even better, as they allow to truly compare amps rather than hearing one amp in isolation :-)
I love my 900 SLX. The red tolex adds extra mojo. I’m sure of it.
Awesome video and sound
i have this amp also the jcm900 slx, ( keep everything at noon when using pedals) i think its the best marshall amp ever produced
I've been subscribed to Arnold plays guitar for several years now.he does some things that get my attention and he also does some thing's that don't but definitely worth keeping him on my subscription list.
This was my main amp from '98 to '05 because I was an Azagthoth fanboy.. fought with it a lot, but hearing you play one makes the tone muscle memory RUSH back in.
Azagthoth didn’t play the SL-X. He plays the 4100.
@@Kevin.Kelly. he never said he did
@@adamnesbitt11 Azagthoth fanboys play 4100’s.
@@Kevin.Kelly. not this one apparently
@@adamnesbitt11 You got that right.
I used to have one of these. Such a killer amp.
The SL-X in crazy underated. Unlike any 900 series , one chaneel all tube and insanely Bad Ass. I had the 5881 version it was a poor mans Slo.
Poor man's slo 😂 any 900 destroys the slo as does the TSL and jvm410
I bought an slx for 500 euros recently. Worth every penny!
Great video 👍
Thans man! Enjoy the amp!
Easily one of the fastest wittiest funniest fun video ever Kyle. It’s gotta be bc you switched to Mac eco 🤓
Definitely a versatile amp. 👍🏻🤘🏻
I have a JCM 900 SL-X and its the best sounding marshall I've ever heard. It doesnt have stock tubes in it I'm not sure if theres been some modifications to it but its insane.
JCM2000 DSL100 for me, but I'm out for straight up brutality.
Worst I have ever had. The tsl100 is the best then the jv410 then the dsl100 then the jvm210 then the jcm800 then the jcm900 in my opinion and the slx is the only 900 I have tried I believe the dual reverb version has to be better regardless of what the sheep say they all say the jcm800 is so good but its useless the dsl100 does that much much better
Do u ever not like anything? I bet ur happy cause u know its going 🤣
@@josephbutler148 You must have had a bad SL-X, & not EL34's. because I had all those amps you have and older ones too like a 800/2204 JCM 2000 DSL 50.. Ths SL-X is one of my favorites. It's classic Marshall with a shitload of gain or not a shitload of gain. Can sound like an 800. Can't do that with a JVM or DSL 100
I’ve got a 100 watt SLX. Love it. More so than my JVM. One thing though, I had to have it modded to handle todays AC voltage. It needed resistors to handle 120v. It kept popping the main fuse then eventually blew all three fuses and the main and messed up the power tubes. After I had already had new tubes put in it. It’s a 96 so made in Britain, the Brit’s didn’t foresee the US power grid upgrades. So if you go buying a 30 year old Marshall make sure it’s ready for more than 110 wall voltage. It’s an expensive mistake that not all techs know about.
Diggin the riffing on this one 🤘
We have similar boost taste. Check out the Maxon OD820. Has the SD feel but the TS mids.
Nailed it! 🤘
Sounds like the blue channel on a EVH 5150iii 50 watt- but more open, less congested. You got to demo the VX KRAKEN- best of the brown tones!
The second gain knob seems to act a little like a resonance knob would. Im looking to sell my jvm210, which i effectively only use the yellow mode of the second channel. So a 2203 or 4 or even the slx would be really cool to own for me
damn that sounded awesome! would be interested to see you demo a mode4
I have the 4500 5881 JCM 900 but it's loaded with 6L6 tubes. Eventually I'll put some 5881 because from the demos I've seen the 5881 is warmer than the 6 L 6
☆ SOUNDS GREAT..And I Like that "Les Paul".🤟
Thank you! MY too :)
Love to hear you play a mk3 900. I have one it is killer. I also have the hated 900 DR, but I like it. Too many tone snobs out there
Agreed. Luckily I have both of those in my possession at the moment so those videos will come soon.
@@belligerentamateur that'll be fantastic, especially if you do the DR, put paid to all the snobs out there who say it's crap. As for the mk3 and the SLX, dual master volumes are really helpful
I play my lp in drop a and it helped a ton with the g string losing tune.
Fun channel! Subbed
Would be interesting if you could find a Marshall 9000 and 9002 preamp. They were very metal sounding
I have the EL34 version. Mine had problems right out of the box, and I hated it. A few minor fixes later, it sounds like an amazing Marshall. I had always assumed it was an awful amp 😂. Glad I kept it. It’s tight, growly, glassy, and capable. You can play SRV or Pantera on it.
most useful sl-x demo on youtube. I wonder if the two gain-knob setup is similiar to how the VHT Deliverance treats it. Anyway sounds good!
Thank you, my man. Yes and no to the gains being similar to the VHT. Technically they operate differently but produce similar results.
I''ve got the JCM900 SL-X with el34 tubes. I think the 5881 version sounds better.
I think Marc Okubo used a JCM900, it sounded so sick! I know Trey from Morbid Angel used one for a bit, but I wanted one immediately as soon as I found out Marc Okubo used it! It sounds siiiiiiick!
I nerd to try my SD-1 with my JCM 2000 and 900 because i run them with an "808 tubescreamer" by berhinger but I have an SD-1 for my bass rig
Since you mentioned the g string thing, have you seen the Robert Baker stringing method video?? That's the way I string my Sg and it stays rock solid tuning wise.
I'm actually looking for one of these in the 212 combo version. I have a JCM800 4010 combo amp, I just installed the Eminence DV-77 speaker and what a difference. I'd just love to get my hands on a JCM900 212 combo! I was surprised you didn't try a BOSS HM2 lol. Great content, cheers!
I have one but im still experimenting with it. i think Reverb has em for like 1000 bucks. i just wish i didnt have to crank it so much Im not really sure how to use the thing. i also have a new dsl 40 cr. i have a fender blues delux 2x12 also from 1993. i run a tube screamer thru it and i like it but again i have to play them too loud
@@spitfire27028 something I've noticed with my Jcm800 is the type of boost you hit the front end with. On my pedal board I have several in line. I have an Ibanez Nu-tube screamer,MXR zakk Wylde overdrive (cream version), BOSS 40th Anniversary SD1. Now keep in mind I'm running a stereo setup thorough an Earthquaker Swissthings pedal and it has its own adjustable boost. So all the boosts work ok, sound good, but when I want to hit the preamp hard, I use the Ibanez Nu-tube screamer, it's an 18 volt and drives the front end better then an original. Then when I want a little more, I hit the clean boost on the Earthquaker Swissthings pedal and it's perfect. Some ideas for you to check out maybe! That Earthquaker Swissthings as well as the Ibanez Nu-tube screamer are highly underrated and very under utilized!
Ty for the reply. Im curious do you run a tube screamer thru the clean channel or the dorty channel?
@@spitfire27028 well it's different for each amp, and this is where trial and error comes in. On my Carvin X50B I use to run it on the dirty channel, but now I run it on the clean with the Marshall. The Marshall Jcm800 combo is a single channel so no choice really , for me I turn down the treble and turn up the presence and Pre amp. I also swapped out my Celeston Wolverine speaker for a Eminence DV-77 Mick thomson so that drastically changed sound (for the better lol). I do gain stack the Ibanez Nu-tube screamer with the clean boost on the Swissthings, but I also gain stack it with the Boss SD1. When I add the Peavey stereo chorus 212 with thoes amps, it's on the Lead channel. Hope that makes sense, maybe a bit more then you wanted to know lol
That guitar is what i checked out😉👌👌👌👌👌
Got the EL34 2500 head. It needs a MXR 10-band in the loop to fatten things up. But yeah, it rips
Or just a TC Mini spark in the loop. I also have the bass increased on it. My tech said for some reason the stock bass setting are lower than most Marshalls so he uped it to what other Marshall's are.
My 3rd amp ever was a 100w JCM900 dual reverb head with a 1960 4x12, my dad made me get it 😊. It did not have much gain at all. I know this slx version has more gain but the more videos i see demoing JCM 900's the more i think my one was broken, maybe a preamp tub was broken? but i did not have the experience to know it 🤔. Got me into pedals though 😁. I also had JCM 2000 TSL60, TSL100 and DSL100 but i have to say the JVM is marshalls best ever i think.
Probably had an issue, the HGDR has a good amount of gain and gets very metal with a good boost in front!
Would love to hear you get some tones out of a DSL 100 hr. Kind of been struggling with mine.
Huge fan of the 900 series. My main amp for a long time. But im loving your Les Paul there. Is that available?
That’s an impressive Marshall!
Sounds really angry 👍
"Too much coffee"?!
DUDE!
I have severe ADHD, on meds for it, and also mutually enjoy coffee!
I'm a freakin' RIOT at work in the morning after an espresso!
Hahaha!
My first band in the 90's (I was the drummer) had two guitarists with both a JCM800 & 900 cranked onstage.
I know some people complain about certain revisions, but IMO? The JCM900 absolutely SLAYS!
Great demo bro!
Peace out!
I had a 5881 SL-X and it was cool, but it was woofy. Admittedly I didn't spend much time with it to understand the way the pots affected the sound. It sounded great for the classic rock, but I didn't get the sound I was looking for. I preferred my VHT Pittbull, so I moved it along. I did have a JCM900 MK III and for me, that was my preferred version of the JCM900 lineup. It was a 50 watt EL34 version; and because of that I would love to try a 50 watt EL34 SL-X at some point. You did get some great tones from this amp!
I own a 50 watt SL-X with EL 34’s …. Dude it sounds way better than this one on the video and then I installed the legendary tones lynch mod and it became a better amp ……
Cool ya had both models...👍The MK-III was the 800 carry-over I didn't hear much about till way later. Sadly....boosting an SLX to get the preferred response/feel seemed childish back in the day.....EMG's were the preferred problem solvers I guess. Great amps! The VHT's out of the box were able to provide what so many were looking for at the time......but seemed to only shine with VHT-CL-50 speakers? My Ultra-Lead was very dry sounding and didn't gel with V-30's......which ended up being a deal breaker in the end. peace.
@@Auen73 I prefer to not have to boost an amp, but anymore I have come to just expect it. I had a VHT Pittbull 50CL (that I gave to a friend) and currently own the 100CL. I also own two FatBottom cabs, a 4x12 and 2x12, that had V30s. I really dislike V30s so I pulled them. Right now the 4x12 has Jensen Raptors and the 2x12 has Jensen C12K2s. They are both better than the V30s, but the C12K2s are my favorite.
@@xvx6663 I didn't know you can do the lynch mod? Geez, but why would you need it? I've had my 50 watt SL-X EL34's for two months. It amazing.
@@guitarexpert2245 idk, without the lynch mod I did not like the sound as much… then when I installed it, the sound got tighter… and when I play it at low volumes in my apartment , it still sounds heavy and mean ….
comparassion between JCM 900 SL-X 5881 vs peavey vtm 60 please!!!
He said Peepers Dirty Tree hahahahaha close enough. Always dig the videos man. What happened to that Egnater you demoed a little while back?
tube amp are hard to beat. I wish I could get this tone with an hybrid amp with only one 12ax7. I'm sure it's possible and I never heard one yet, with a tone of good distortion
The SL-X sounds killer! The way it sounded with your drop tuned Schecter really made me wanna make some chugs on my JCM 900 mkiii! Can't wait to see what yours sounds like when you get around to it. *
That tone on the Metallica riff was pretty spot on.
That's a cruel sound! I enjoyed the video! Thanks to you, I bought it too! Can you make a video using hot load mod v2 and Lynch mod on this amplifier?
I dont think those mods work on these amps.
@@lowqualityguitarvideos It says it's possible on the website. Is it not possible because it's 5881? I don't know because I didn't ask.
@@young3879 oh okay maybe im speaking out of my arse without doing due diligence. Im thinking the original soldano hot mod was made for more simple 2203 type circuits. ignore me
Great video Kyle, I'm wondering if it's possible to get those nice rich compressed Marshall cleans from this amp, with the Master volume cranked? Or is it just a straight ahead dirt machine?
With the one gain down (can't remember which one) and volume cranked up, for sure!
This thing can be conected with audio interface?
How does it compare to the MkIII?
my man played harms way in a jcm900 demo video so dope
Hey I'm from Texas 🤠
I got a 93 SLX but its the EL34, which is kinda strange since thats still in the time frame of the global EL34 shortage when everything switched to 5881. Both are fantastic amps and ARE the best of the 900s in my opinion
My sl-x is from 93 and it has el-34's in it I love it.
@@thesgkiddave awesome! I love both models but im a sucker for the EL34 mid ranges. From what ive seen, looks like 1993 is the last of the EL34 era as the global shortage kicked in around the tail end of that year and lasted until early 1997, which by then, the 900s had been retired for the JCM2000 series.
Sadly, my SLX is dead right now and needs to be sent off to the repair shop ( something happening inside the heater circuit and is blowing fuses)
Hi Kyle , me personnely i prefer EL34 family.E34L , KT77 and EL34.
👍 MXR 🎸 BEST OF THE BUNCH 😊......EHX SOUL FOOD & CRAYON ( R MY FAVES )
I prever the mkiii that Trey Azagtoth use
I know a harms way riff when I hear it 👌🏻
"Peepers Dirty Tree" 😂
Most interesting about the 900 SL-X, they got a lot of slander due to diode clipping, and it wasn't full tube clipping path.
The SLX is the model that has no diodes, though. The other two models are the ones with clipping diodes. People probably got confused, or just believed what they heard.
JCM900 Models 2500, 2501, 2502 & 2100, 2101 according to google. Which wasn't labeled SLX before 1993. Marshall added an extra tube for the added gain stage of the SLX, where the models are identified 2100SLX and 2500SLX.
I prefer the 4100 personally, cause distorted tones can get dry easy.
what about the JCM900 MKIII High Gain Master Volume 50Watt? also very underrated.
I have that one as well
@@belligerentamateur please do a Video!!😀🤗🦾✨
@@texxhexxmm You have a MK-III Kyle? Yes......please do a video of that Dark Horse that slipped under the radar all those years ago!🙏.........
Had the 50W 1x12 combo. Loved it. My son in law wanted a Marshall and I was looking to thin the herd so sold it to him. As always now wish I hadn't haha.
Who was that at the beginning where you said "post hardcore or pop punk", i know I've heard that riff before
Heard about this amp when fluff mentioned it and immediately looked it up and came here for “scientific research” sounded good then all the sudden one popped up in my area and I was like “what the hell why not?” Haven’t looked back since the thing is absolutely B R U T A L and for $800 how could I go wrong! Love it and never getting rid of it, fun fact someone along the lines had replaced the tubes with ruby 6L6’s and still sounds very Marshall-y and heavy AF awesome video Kyle made the decision easy!!!
What is that riff at 6:17 from? He plays it all the time and I swear I know it but can’t put my finger in it, and it’s driving me crazy
I have this same amp and it started doing these static noises when you don't play. I noticed yours is doing the same thing. Any idea why?
I love mine.
I have one too, and it does that. I got it serviced once, and they said it was in great condition and that was normal, I think it's to do with the power transformer, but don't quote me ...
This is the amp Darren from Sadus used for years!
Really killer amp and guitar pairing. If you're looking for another underrated, inexpensive and awesome high gainer, you might like a Laney GH100L. They're basically like a JCM 800 2203 but with an extra preamp tube that can be switched in/out as you wish, so you can really get a lot of extra distortion compared to a stock 2203 if you like. Brutal, powerful sounding amps that sound great even as low as 2 on the master volume. They can totally get into thrash without any pedals cause of the extra gain stage,
My first tube amp was a Laney GH50. Loved that thing! Sounded great! Got it for $300 in 1998!
@@GabeHelma Funnily enough I just went halves with a buddy on GH50L. We took it back to his studio for a test and were absolutely blown away, so much aggression and available gain but still great cleans. For £100 each I think we did pretty well!
Nope. Friedman
Thoughts on the jcm800 2210? I loved this amp right before you turned on the boost, reminds me of my Ampeg VL a bit but different, I feel like they'd blend well together
You will find out very very soon
@@belligerentamateur 😳😳😳
Surprisingly capable Marshall sound. Good stuff.
Check out a Laney gh100. People often say that its a poor mans jcm800, i had it and i thought it was a homage to an SLX
Tone jail😂😂good one!!!
people shit on the 900 for good reason, but the SLX is an unstoppable machine. total sleeper
sounded heavy, sounded great, sounded like a marshall. people like to just spew out the typical rhetoric, "BUT IT'S NOT AN 800". The 900 is my preferred Marshall if only for it's tonal versatility compared to the older Marshall amps.
Yes, that SD-1 makes a huge difference. 👍🤘
Over the last few years I’ve revisited the 900 series and they are all good amps that don’t really deserve the flack they get. They are great workhorses that get the job done, but with that being said, an 84-89 Split Channel 800 is in the same ballpark, but does it much better.
The JCM 800’s also have the added feature of being nigh unaffordable.
