What are the odds that within a two week period I'd get TWO late 60s era Gibson amps for repair? We recently saw a two-channel 112 combo - the Minuteman model GA-20RVT. This one is the 110 combo GA-15RVT Explorer model. This example came to me in very original condition (except for the Fender Eminence speaker). We'll take a look at the guts in all original condition first, then we'll change filter caps and add a 3-prong cord before a final tone test. I think the demo portion will put to rest any notion that late 60s Gibsons are somehow 'bad' amps. This one sounds killer!
