Gibson's GA-20 amplifier has long been considered by vintage enthusiasts as one of the very best amplifier models to come out of Kalamazoo. Stretching back to its introduction in 1952, it has proved over the years that some of Gibson's designs could really give Fenders a run for their money. We'd confidently make the argument that a well-tuned GA-20 could push some historically great Fenders from the same period off to the side - no joke.

So what makes this 1956 GA-20T so special? It's got the perfect combination of looks, sound, and tonal versatility that will keep you smiling every time you plug into it.

Closely related to Fender's Tremolux, the GA-20T is a two-channel 1x12 combo with Normal and Tremolo channels. The former uses a 12AU7 preamp stage with the latter incorporating the 5879 pentode. This gives the player two different preamp flavors, with different gain voices, respectively. Combined with the great tube tremolo (that's where the 6SQ7 tube comes in), it's got great tonal range for a low-powered amp.
