Gibson Falcon (6BQ5) - Tremolo preset

Verified · 90/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

This later Gibson Falcon swaps the original GA-19RVT circuit for a 6BQ5 (EL84) output stage and a diode-rectified supply. Two channels each have their own 12AX7 input stage with bass, treble and volume, and channel 1 adds tremolo driven by a transistor. A 12AX7 drives a spring reverb shared by both channels. The voice is bright, chimey and compact, in the low-wattage Gibson combo tradition.
