Ampeg Gemini 22 GV-22 - Channel 1 preset

Verified · 85/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Ampeg Gemini 22 GV-22 is a two-channel guitar combo. Each channel has Bright and Normal inputs, two 12AX7 stages, its own Volume, Bass and Treble, and Ultra Hi and Ultra Lo switches. A 6CG7 drives the spring reverb, recovered by a 12AX7 with a Dimension control, and a 12AX7 tremolo with Speed, Intensity and Afterbeat can run as tremolo or vibrato via a photocell module. A 7199 inverter drives two fixed-bias 6L6GCs.
