Vintage original 1966 Gibson GA-20 RVT Minuteman combo amp.
Clean and all original with footswitch, too!
This was loosely Gibson’s competition for the Deluxe Reverb.
A pair of EL84’s for about 18 watts of output, while of course the Deluxe Reverb pushes its 6V6’s up to a rated 22 watts.

Excellent warm vintage tone, a wonderful recording amp and a fine example.
