Hi Again,
yea I'm thinking 80s too. Once the Trace Elliot acquisition happened, all the amps were tube amps, and at first made in UK, eventually Gibson moved the MFG to the States, but soon after, they stopped making the Goldtones. Too bad because they were very cool amps.

That's too bad that customer service hasn't replied yet. Maybe some one will show up here. There are a few guys that do come here and contribute.
I have a Gibson Goldtone GA30RVS (see link for the PDF above) That one is a Class A Stereo combo tube amp (I think I got it back in 2002??). (it's essentially two GA15RVs bolted on a single chassis with 2x12s.)
Of course, they are no longer made, but you might find one in the second hand market if it's of any interest. (be forewarned, this sucker is heavy - about 90lbs) They are probably hard to find at this point. Not sure..
sounds great tho, it's got that distinct class A tone (think VAX Ac30). It's quite simplistic, volume, (push/pull - gain on, gain off) a tone control (well it's a bit more than a tone control) a spring reverb (the reverb is actually quite cool - "surround sound" and it does work.) and a bright switch. 2 FX loops (Stereo) Series and Parallel, A dual footswitch for gain on/off and reverb, and a single foot switch to by pass the FX loops.
Not sure if you're looking for channel switching capabilities, which this amp does not have, but a good over drive pedal will work too. It will start to break up at about 10 o'clock, but it's very loud at that point, so unless you're looking to alienate all your neighbors, will need to front end it with something.
Good luck in the search!
