Gibson Maestro Reverb-Echo GA-1 RT Model Tube Amplifier (1963), made in Kalamazoo, Michigan, serial # 109534, tweed finish.
Height is 14 in. (35.6 cm.), 19 1/2 in. (49.5 cm.) width, and 7 in. (17.8 cm.) deep.
The GA-1 RT was manufactured by Gibson for its sub-brand, Maestro. Intended for use by accordionists, the Maestro Reverb-Echo functions as a stand alone amp but derives its name from its proposed use in concert with a second amp to produce a reverb effect. Although it is at this time unclear how one might achieve this effect sans reverb tank or output jack, the GA-1RT is a fabulously raunchy little amp. With two controls (one to attenuate volume and the other being a speed control for tremolo), an 8" speaker and the somewhat odd 3 tube compliment of a 12AX7, 6BM8 and a 5Y3 this amplifier is cousin in tonal characteristics to the big box tweed Fender Princeton's that preceded it by a few years with the added feature of tremolo.
Some text worn from chassis, a small indent on the top, scuffing scratches and a single burn mark indicate that this was well cared for if often used little practice amplifier. Excellent Condition.
