This is why I only buy old solid states with no digital stuff or tube amps It's more expensive usually but I know they'll last longer than anything with a computer chip in it and sound better too

Just buy a modeler and DI at that point

You need advanced degrees in computer sciences to work on a freakin' toaster, these days It's not a particularly good thing

Brad the digital sections to repair them they just throw entire new boards at them, no replacing caps or anything, just plug in a new one
Comment from : @bayshorepark1231239

A decent microscope, a decent rework hot air station, a decent amount of patience I had to fix a lot of SMD boards, almost always there are leaky caps (SMD variety), cold joints and if anything with custom firmware or any custom ASIC goes, utterly unfixable On top of not having any schematic most of the time Swapping out opamps is actually easier than with thru-hole components, just heat up, tweezers make go fly across the room, clean a little bit, new ic, solder, done

Do you do a Crate GT200 DSP 2X12? It doesn't turn on, no blown fuse, the DSP is a separate circuit board Hybrid tube/solid-state 2x12 It's been kept in an Anvil case pretty much since new Modeling amps are use and throwaway I do have an early modeling amp, the original Roland Micro Cube I love it When it's done, I'm planning on coverting it to a tube amp I have a schematic that was drawn out using a single ended hand wired tube amp using 5878 and 5672 tubes I looked all over the place and couldn't find how to get in touch with you
Comment from : @tolerbearALTII

If your buy one of these amps, buy all the warranty you can find if you plan to keep it These were not designed to be worked on - other than perhaps component replacement, ie, if something on the board is dead, replace the board
Comment from : @ourlifeinwyoming4654

Surface mount? Forget about it Regular PCB? Maybe
Comment from : @RodVonLongrod

Had a Marshall Code 25 or 50 kept blowing the fuse on the power supply Turns out it was common amongst some of them I emailed Marshall directly because I couldn't find a schematic for the power supply, they wouldn't send me one because I wasn't a Marshall dealer, and wouldn't even sell me a new one Last modeling amp I'll own I prefer simplicity these days, glad that happened because I relied on that thing too much for my tone
Comment from : @justinsixx90

Yeah , I’ve got two stacked in the corner One is the VT100X a guy gave me after it sat in his trailer for a year Only got used twice But never worked even once for me And no tech in the country will touch it with a fifty foot pole
Comment from : @theofficialdiamondlou2418

It's not that bad Any decent electrician could work on one Now if the IC goes out and you can't replace it, that's a different story
Comment from : @yummyklown9226

All surface mount I bet, Good Call

hi Brad you're a wizard 🧙‍♂️!!!!
Comment from : @zandig666

Hung on your time foolin with it Damn pc boards bad enough
Comment from : @hadleymanmusic

True Even though I had crush on this (before I knew better anyway) The thing is I'm not even sure who would work on it Too delicate for amp repairmen, too weird for common electronics service
Comment from : @tomastuharsky

Wait a minute What was the symptom? While I agree that boards with lots of surface mount ICs would be a major hassle to track down a defect, the symptom could point to a power supply failure, or output amp failure Both of those circuits are relatively easy to repair I've made money and lost money repairing modeling amps It depends on the symptoms and the failure history of the particular model
Comment from : @MrDiscomfortzone

Modeling amps are basically garbage to me All my amps are tube driven
Comment from : @erikavery8569

The actual obstacle is probably like a line 6 I looked at, company will not supply you with tech data to work on them But I would still take a look as it is just as likely to be simple, versus some kind of exotic digital problem A tossup Just don't make any guarantees to customer
Comment from : @tomsherwood4650

Smart call, if it has IC's and PCBoards I dont touch them brSometimes I'll look into it and it's obvious a resistor is burnt or electrolytic is fried and it's a simple fixed but if that doesn't fix it, sorry
Comment from : @gruberstein

Haha 😂 I work at a shop repairing guitars and tube amps We don’t even take in solid state amps let alone PCB’s with SMD parts on em…nope! No thank you
Comment from : @NickP333

A lot of the newer amps are junk anyways with a lot of fake parts 😂😂😂 they're not built to last anymore throw away junk
Comment from : @SS-mj2mq

He'd be better off taking it to a computer repair shop
Comment from : @JohnSmith-ki2eq

Yeah… had a similar Vox amp years ago (2003) that I wasted a bunch of cash on One of the boards went out within a year Took it to a reputable amp wizard and he immediately looked exhausted just seeing that hunk of crap coming through the door I just gave it to him to salvage whatever he could Lesson learned…
Comment from : @ck185

The best repair for those is the dumpster
Comment from : @bskitchenriffs6522

Same with those overpriced disposable Fender ampswhen something goes wrong,folks are usually gonna have to trash them
Comment from : @rickya3877

That dude at psionic could do it I'm sure
Comment from : @SEXYBATMAN69

Vox amps like this are crap, like the tiny turd MV50
Comment from : @nevillegoddard4966

If the guy is partial to vox modeling🫤 he could use the amp as a cab and he could get a tube cake pedal with a vox modeling pedal board🤷🏻brBy the time someone charged him for the work he could buy that stuff
Comment from : @aaronjackson6273

a modeling amp is basically a computer with a high-powered speaker brto work on that stuff, you have to be 2M repair qualified, and have a special work scope to see those TINY traces and ic leads
Comment from : @carcarjinks1430

Those amps are pretty much disposable aren't they? Like old laptops
Comment from : @jasonbates2687

I need to fix my tweeter in my B & W DM 220 speaker, i received the diaphragm for it and would like some advice on how to install it if you could do that i would be ever so grateful!
Comment from : @JaniceLalla

That’s why it’s better to save your money to buy a semi decent tube amp, even if you are just starting out
Comment from : @mohamedtlass3842

That Randy Watson shirt makes my day
Comment from : @justincase6151

Why are people so scared to work on things with ICs? ha IC's honestly hardly EVER go bad its usually a cold solder joint, or a loose wire connection with these types of electronics Not saying they are better, cause they DEF arent lol, but just not a whole lot of parts that fail on them Now things with BGA chips on the other hand haha those are a PINA to fix lol
Comment from : @VashStarwind

I have a Peavy JSX i need gone thru How do i get in contact with you? Assuming its its something youd want to work on
Comment from : @JaredGrissett

I once owned one of those VTX amps 20 watt great little amp but the usb socket broke took it to the local tech, one it was getting the parts two the cost of would be just as much as the amp, that's how they are designed so I sold it the amp did work but to access the tone room was through the USB ,
Comment from : @canadianintheukbrian

Vox actually went crappier than their valvetronix series? Wowthese companies just do not care about putting out good products that last
Comment from : @moogman5

Good call 👍
Comment from : @DavidSmith-ni7ow

Basically a Bluetooth speaker with a built-in guitar amp digital simulator No way to fix that if the fault is outside of the analog circuit Some people could troubleshoot it, but the question is if you can even get any of those ICs let a lone the programs that you will most likely need to load onto some of them brAnd these ain't the simple and rugged old school digital ICs from the 80s which basically last for ever either brIn the end, it will cost more than just replacing the whole board if you can even get ahold of one
Comment from : @westelaudio943

SMDs in a f**kn' iAMP/i !!! brOne, invisible fracture and you have a door stop instead of an amp And what do pc boards hate more than anything (especially SMD)?br1: Heatbr2: VibrationbrJust strap your laptop to the engine well of your car, and take a bet to see how long it lasts That's how stupid these designs are I hate the fact that they charge good people to get an established name brand, sometimes a particular model (Like Fender does) And what they get is a weak,disposable product Anything is only as strong as it's weakest component Anything
Comment from : @ravenslaves

Brad do you do pedals I have a Looper station RC-2 the powers up but it doesn't work,I think it's got a bad chip? Not kidding and I don't know how to get a hold of you any other way
Comment from : @dorfsteen

cell phone techs gonna be the new amp techsbreven if you could get the machines to make old school amps point to point style the manufacturers would still charge 5-10x the price of a starter amp
Comment from : @kazzTrismus

Yeah f*** that
Comment from : @mark5150ty

Actually, that was the first Vox modeling amp line made & maybe the best sounding of all modeling amps since My amp gear since 1980 is a 79 JMP50 Marshall combo & and a real vintage blackface 65 Fender Twin
Comment from : @ErnieDouglas

I'm always thinkin why these new companies won't make some simple design combo amps that would be with circuit that's easy repair and build and you can sell it cheap Every component from the mid-fi qualty/price range Basic speaker No digital but it could be transistor couse it's cheaper to make and just fiddle the circuit and EQ to fit the speakers tone No this fancy shit that can't be repaired
