Bro your playing is totally fine, your tone (from your fingers) is solid, and you play in TUNE! That's a lot more than can be said for 90% of guitarists on the internet!
What a monster!!! Nice work. A good measurement of intelligence is not measured by mistakes. It's measured by how we manage them. You're very humble. Kick ass amp!
I'm not a guitar teacher, but I am a fuckwit, therefore I found your playing at the end of this video rather satisfactory! Cheers, Brazza!
Might have weird values in the tone stack but it sounds great. I would definitely buy that over a Fender or Marshall. Great job fixing it up!
Always amazes me the ammount of work you do. Be interested to know how man hours involved on big rebuilds like this, most people would be suprised. You do good work for sure.
Awesome work. There's cool version of this amp made by different company. Lee Jackson XLS-500/1000. No reverb, all tube fx loop with send and return pots ch 1 with more headroom and no master vol. Those need heater mod too (melting connector). I think all of them came with 5881 Sovtek tubes and could be switched to el34.
The boon dock saints. Greatest movie ever filmed
@@dennismccullough638 , "greatest movie ever filmed" is a bit of a stretch, but it's a good movie. If you wanna see an Irish movie that is fun, dramatic, heartwarming and heart-rending, try "Mickey-bo & Me", about two kids who try to duplicate every major scene from "Butch Cassidy and the Sundance Kid". "Ondine", with Colin Farrell as a fisherman who rescues a drowning woman who isn't quiet what she appears, is another good one. As for my own personal favorite films, it's probably a toss-up between the Italian film "Cinema Paradiso" and John Sayles' "Matewan" about striking coal miners in West Virginia.
Holy mary do you have patience! I would've had a nervous breakdown, changed my address, and hid in a bunker until the customer forgot about it all. Great job! You and Psionic are always in my head when designing and laying out my own amps. Fortunately I am usually aligned with your thinking and avoid the issues that you both cleverly note. But when I am not, it's always an education well appreciated. Thanks!
Impressive job installing/ hardwiring all the output tube sockets and phase inverter circuit! I'm curious to know what the B+ is on the EL34 tubes, and, noticing a bias adjust pot, if the bias is the typical Ampeg capacitive divider that they've used in the past or if they went to a more standard Fender type bias circuit with a tap on the power transformer. Also, is the reverb tank capacitor-driven or transformer-driven?
Ampeg is infamous for amplifiers that don't actually match the schematic or layout diagram; and for that matter, so is Gibson. Anyway, you should be glad it's not a double-sided board because it's almost impossible to trace double-sided boards by eye.
Greetings from Albuquerque. Will keep an eye out for random Ampeg traces. 😂
Very very impressive. Plus a reference to Albuquerque!
The internet is amazing. A guy is creating content about amp repairs and technical stuff which is helpful (and entertaining) for many and we have a guitar teacher making rude comments about playing. There's like at least 2 things wrong here. One, this is not a channel for showcasing guitar wizardry, so it's irrelevant and two, he's really talking out of his ass. Anyone who is a musician or music lover, let alone a teacher knows if you can or can not play instrument and one note is enough. So maybe there's a reason why he has time to share his thoughts on the internet..
Fantastic work mate.
I think you playing is great,Brad. Rock on brother.
5:15 25% excess Fluke in gratuitous shot...I love it! Great video as usual Brad. And you play quite well, F that guy!
Greetings Brad. Great job, you brought the Amp back from the dead.
According to the Ampeg "Story Behind the Sound" book by Greg Hoskins, these amps were built from 1991 through 1995. (The chassis has an internal stamp that says 111991, which is probably the manufacturing date ---- 11/19/91, November of '91 ---- for the chassis, if not the actual amplifier. We use abbreviated dates a little differently here in the US compared to the rest of the world......)
As Lyle would say, that amp has SEEN THINGS, man!
You really do amazing and thorough work, Brad! t actually does sound unique and very cool. I get that tone sits in the mix really well.
Nice work Brad ,Ampeg has thier own sound and I like it ,nothing a pedal cant cure just have to use a 100 foot guitar cord and get away from the beast as it sings ask me how I know
I have one that was cooked the same way. I am going to have my tech do what you did and hardwire everything
Hell yeah, I have one of these and its a work in progress
Also totally worth the work, it kicks ass
What's that "Lock" thing for seriously?!
It's not like someone is going to steal this beast and run away with it.
Nice job mate!
Great amp love the spring reverb it has, the cleans are really great as is the second channel. Have one and love it but to each their own some people like Marshalls i honestly like this and the old VT22. Great video I swapped mine over to EL34 also sounds great looks like you had fun doing the repair. Keep up the great videos appreall the time and effort you put into making theses videos.
Such great work! I admire you patience! And i actually like your guitar playing as well. F#@% the haters
Next time I service one of these, I'll wire an ampule of baking soda in parallel with the screen grid resistors for added fire suppression. Like I do with Mesas.
Maybe include a miniature canister of halon gas for the Mesa amps?😅
Incredible work
Nice work mate, actually great sounding amp...
Hope you've nailed the lurgi!👍🏼
G'day Brad,
That was from the Boondock Saints, just before Billy Connoly gets his 6 guns off!
There was a firefight! Boondocks Saints
Thanks for the video.
Ridiculous amount of work but I love how it sounds. I’m definitely into the Ampeg or Orange, low-mid or kinda boxy mid thing. This thing kind of reminds me of a JTM45 just not as tubby on the low end. So you’re tying the fly back diodes between the plate and cathode to stop an HT short to ground through the cathode?
Would be cool if Lee Jackson commented on how great your repair is on this amp.i have owned 2 of these amps but never keep them. One of my favorite band from the early 2000’s was Hey Mercedes. I saw them one time they had one and found a half stack for $400 at a pawn shop.
nice work mate! long time no see.
Just want to commend you on the work on this beast, Brad. Playing is definitely better than mine too! Hack power chords supreme over here!
The amp got its maiden run last night at the Duke of Enmore and ripped hard!
So good to hear, mate!
I love that venue, and it's literally across the road from our brother-store Dr Gear!
The burgers there are fantastic.
@@BradsGuitarGarage, how is "Six" doing? He's had a rough go of it lately, I'm sure. I hope his coping skills are up to it.
He's not great. I'm just staying in touch with him as that's about all I can do.
@@BradsGuitarGarage , very sorry to hear it. Tell him we all wish him the best.
Mahalo Brad!
You really do a Sterling effort old man :)
dude that is some great work!
" There was an earthquake! A terrible flood! It's not my fault, I swear to God!" 🙏 That might be before Brad's time, but sime of you will recognize that movie reference.
That movie was my favourite from the age of about 5-12YO. I think I watched it 1000 times and learned so much about music by tracking down the works of all the musicians involved. They were lucky lads to have a SNL sketch blow out to such a respected musical endeavour. We had the soundtrack on CD and I forced the family to listen to it on repeat during road trips.
@@BradsGuitarGarage , So, which of the 3 main characters do you most resemble, personality-wise: Belush, Aykroyd or Carrie Fisher? My pick for your doppelganger would be Carrie Fisher! 🤣 By the way, I actually cooked hamburgers for Matt Guitar Murphy once; I was a doorman/bouncer and night-shift cook (my brother was the other bouncer) at a small club where the Shaboo Allstars, containing some of the Blues Brothers bandmembers, used to play occasionally (bassist Donald Duck Dunn was definitely one of them, and Steve Cropper might have played there on a night I wasn't working). Anyway, Murphy asked me to cook him a couple of hamburgers and told me he wanted them well done; his exact words were "I mean, I want them *burnt*". Knowing that the boss bought cheap, premade hamburger patties and they wouldn't be very good if cooked to the point of being well done I tried to dissuade him, but he insisted. The burgers came out about the size and texture of hockey pucks ---- and then he complained about it! This is even funnier when you remember that in the movie Jake and Elwood rescued Murphy from working in a restaurant kitchen owned by Aretha Franklin!
PS, the Shaboo Allstars got their name from a relatively short-lived club, the Shaboo Inn, not far from where I live now; a dive bar, pretty rundown but which for a couple of years played host to some great shows: I saw a few shows there including Johnny Winter, Elvin Bishop, and Arlo Guthrie. Bonnie Raitt played there several times; The Police played there on their first US tour, to a couple dozen people, obviously before they became famous. I'm sorry I missed that show! Anyway the club only ran for 3 or 4 years and then burned up mysteriously in the middle of the night when they weren't open; Rumor has always been that the fire wasn't accidental, and was torched for the insurance, but it's true that the place was run down and a terrible fire trap. Anyway, one of the original owners of the club went on to form a sound renforcement company and was the singer of a part-time jack of all trades band that became the Shaboo All-Stars.
What was with putting those tubular Ace Locks on amps back then? Add a coin slot & a coin box and it's a pay amp. The good picks for those locks are about $600USD now, which is about half what I paid years ago. Those locks were on video games, vending machines, slot machines, video poker, and some industrial equipment and fuck all if I ever had any keys that fit anything, but they wanted it fixed. Add $100 just to open the lock and another $75 to make working keys. I forget what the key cutter cost. Not that much and the $1200 pick automatically decodes the lock bidding.
No idea, mate.
They were on all the PC's and they were the new "happening" tech, so I guess they all just panicked and put them on everything!
I wasn't aware of Ampeg using keylocks on any of their later amplifiers but back in the 1960s they were building custom-order amps for session musicians in the New York area who would chip in together and buy amplifiers for each of the studios they worked from most often, and then when they went to a session gig they didn't have to carry an amplifier with them. No one was allowed to use them except for the people who had contributed to purchasing them because they got their own key. You can probably do a Google search for the so-called Ampeg "key club".
Fire damage right next to a label warning of potential fire damage Oh the irony
If it makes you feel any better, your guitar playing is better than mine.
I'd say this might be an interesting sounding amp in stock form. I wonder what the high gain would sound like with a Tubescreamer (to tighten up the low end).
Man, a few value changes and she'd be an absolute beast! Pity about the construction techniques!
Those Svetlana's have that famous russian flying saucer getter, don't they. So no doubt what the origin of those tubes is, even when there was no visible markings left. 🤓
Nice
It's a choocher 👊😎
Boondock Saints !
Predator.

I don't know WTF is going on with that flickering at the end, legends.
Great stuff. I actually dig your guitar playing. I'm thinking that you must be playing in a band because of the ideas and themes you play. No need to keep it at minimum.
It's amazing that all the review channels are a wank-fest for their lead playing ability when for 99% of the guitarists out there 99% of their playing is basic rhythm stuff. I play rhythm when testing because that's what matters the most, but I will work on my lead work as that can tell a lot about an amps performance when it sings at high output. I'm a work in progress and I should be a lot further down the road than I am, but there are only so many hours in the day, unfortunately. At any rate, thanks for watching, legend!
@@BradsGuitarGarage, Jimi Hendrix purportedly once said that he wanted to burn Eric Clapton because Clapton didn't play rhythm. I watched a documentary about Mike Bloomfield on TH-cam awhile ago and kind of thought the same thing to myself, didn't this guy ever play double stops or chords? Anyway as Lyle Caldwell has pointed out, you kind of need to play odd chords to see if there are any strange oscillations or parasitic behaviors. Johanne Segeborne in Germany is an excellent player, but he's got a video up where he's playing through an old Ampeg V4 and although most of the people thought it sounded great, me and a few others were like, this amp doesn't sound right, there's blocking distortion and strange behavior taking place, and the reverb didn't work either which makes me think it hasn't been properly serviced in a long time, if ever.
I do love Johann's work, but I don't think he's very technical.
@@goodun2974 FYI Johan Segeborn is from Gothenburg (Göteborg), Sweden
Haha what is it with ampegs and fire
Does Ampeg still use special rubber isolation mounts for their big amplifiers?l
Whoever that snarky guitar teacher is that criticized your playing, I hope he loses some students over it. If he treats his students like that he probably has a lot of turnover between them. Some people never learn that you catch more flies with honey than you do with vinegar...
What is the purpose of the lock near the standby and power switches on the front panel? Was a key necessary to turn on the amp, or was it necessary to open the lock to remove the chassis from the cabinet?
Keeps the rabbits out.
It's to keep your brother from using your shit
@@BradsGuitarGarage, To keep the rabbits out you need a rabbit proof fence! That's a joke that perhaps only Australians will understand. Anyway, on custom orders,, Ampeg used to actually equip their amplifiers with a locking key to turn it on and off: studio musicians in New York would get together and purchase amplifiers for the studios they worked in the most and then each of them got a key, so when they did session dates they didn't have to bring an amplifier along, but nobody else who wasn't part of their "key club" group and hadn't paid toward the purchase of these amplifiers would get to use them. I don't know if they did that on any of the later models but it was definitely a thing in the 1960s. [Edited to spell "key club" correctly]
@@BradsGuitarGarage , Also worth noting for those haven't seen it that "rabbit proof fence" was the title of a very good Australian movie about an extremely sad historical event.
@@goodun2974 That's interesting. Similar to the concept of a flying club plane, where members of the club each own an interest in the plane and share in the maintenance cost, etc.
The playing is to check the amp and IT voice not Brad's playing . Sounds like the "teacher" missed the point of the demo !
Boondock Saints
big problem s
:)
Why does it have a lock on it??
Must feel good to be back on the piss...
Not really TBH. Might give it up. LOL!
I love your videos matey. I also am another f$#kwit useless guitarist but I don't give a shit what anybody thinks so it doesn't matter. You play better than most I've heard on TH-cam. 🤘🤘🤘✌😎
Ampeg shouldn't of taken that left turn when designing it.
They ended up at Pismo beach lol
@@vadenk4433 With all the clams they could eat ;-)
Still, you have to wonder, if the support parts were robust enough, if the tubes would have melted all the way thru instead of just distorting.🙂
I have seen that happen on other Ampegs, yes!
One where the glass actually made it all the way to touching the anode before it lost vacuum!
