Gibson GA-6 Lancer - Microphone preset

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

The GA-6 Lancer is a small Gibson combo with separate Microphone and Instrument inputs, each with its own volume on its own 12AX7 triode, and a shared tone control. A second 12AX7 drives a push-pull pair of 6V6s through a 5Y3 rectifier. The 6V6 pair gives it a warm, round clean sound that breaks up smoothly when pushed. This is a different circuit from the 1950s GA-6.
