I have this little Guild "Model 6" amp that I've loved for years. I've been wanting to clone it. If I were to open it up and take detailed pictures of the interior is there any way someone could make a schematic and BOM for me? I would pay maybe up to $100 for just the BOM/Schemo, parts not included.

I love, love, love this amp. Dimed, it gets you about 90% of the way to a Marshall. Seriously, at a rehearsal once this guy's Marshall crapped out and we mic'd it up through the rehearsal PA and after the first song people were pretty stunned. Anyway, is this even possible? Would anyone here do it for a little extra cash? The thing is, I'd want a complete BOM, there couldn't be any, "well, I dunno about this piece" because that's the kindof thing that always stops me in my tracks.

If some preliminary pictures would help to even answer this preliminary question, let me know.

Thanks,

Have you tried looking for a schematic in The GT Tube Amp Book?

It's a solid state amp. And I don't have that book. So, no. I have tried googling this amp many times and it's got almost no web footprint to speak of. I seem to be alone in loving / knowing about it.

Edit: It's just a little bathroom amp. I don't know if the "6" refers to the speaker size or the wattage, or both.

Mebbe ask here?

Or here?

Didja see this? (" In the early 1980s, they continued on with this series with a line of practice/beginner solid-state models. Models include the Model Four, Model Five, Model Six, and Model Seven.")

I found this:
"MODEL 6 Guild Guitars Guitar Amp 1982 - 1985
Description: 6" SPEAKER,REVERB Power (Watts/Ohms): 10"

Do it look like this?

That's my baby.

Looks like a mini-Boogie.

That's what I'll call it the next time I try to impress someone with it.

You should call that Guild amp that, also.

Oh crap, that went right, er, under, my head. (As it were.)

Don' worry, the puns was, eh, also cheezy.

If some preliminary pictures would help to even answer this preliminary question, let me know.

Some photos if the insides might help estimate how much work it's going to take.

It could be such a mess inside that it won't be easy to reverse without physical inspection.

It could be full of unmarked or custom marked parts that are significantly harder to reverse engineer. Not impossible, but an order of magnitude when it involves the level of work required to decipher that the unmarked chip is really just a 741. As old as it is, it might also contain obsolete parts that aren't easily found.

Or it could be so sleek, well engineered, and obvious that a BOM just logically drops out of the sky.

It's almost definitely going to contain a custom PCB that you'll need to clone. What are your plans in that regard?

I was going to wire it point to point or on perfboard instead of a PCB. I looked in there once and it really didn't look that complicated, but that was about a decade ago. I'll pop 'er open and snap some pics next chance I get.

I just realized, I'd be willing to send it off even to someone who'd undertake this. I'm crazy, huh? Great bathroom amps can just be had for $100, eh?

OK. Jesus. Sorry about this, but after looking inside, I've come to a decision. The fastest, easiest, cheapest and best way to clone this amp is to set up an alert on eBay. In case you were wondering...
