I’ve never owned a Gibson amp, but I see them around and always think they are interesting. Then a GA-20 showed up on eBay and it caught my eye for a couple of reasons:
1. The GA-20 is very much like a Fender tweed Deluxe. Both have two 6V6 power tubes (maybe my favorite power tubes), simple controls (volume, tone) and compact cabinet with a single speaker.
2. This GA-20 was really cheap at $225. It was cheap because it had been recovered in smooth, black vinyl and has a non-original, non-vintage 12” speaker.
3. Maybe it would be a good project to either restore back to original condition, or mod into a killer little amp.
So I bought it. With shipping, just under $250 invested. Here is what it looked like when I got it:
