Gibson SG-212 - Channel 1 preset

Verified · 88/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The SG-212 (Gibson Model 212) is an all-transistor combo with two channels, two inputs each, and volume, bass, midrange and treble on each channel, plus a Normal/Effects switch. The effects are a transistor-driven spring reverb and a photocell tremolo with rate and depth, each footswitchable. The mixed signal feeds two identical transistor power amplifiers, each driving its own 12-inch 8-ohm speaker.
