Verified · 83/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Ampeg GV-22 Gemini 22 was a mid-1960s guitar combo delivering 22 watts from a 6V6 output stage. The 6V6 power tubes gave it a slightly sweeter, more compressed character compared to 6L6-equipped Gemini models, with a natural breakup that made it appealing for blues and early rock playing in addition to clean country and pop styles. The Gemini 22 occupies a sweet spot in Ampeg's guitar lineup between the smallest student models and the larger professional combos.
