Gretsch 6165 - Channel 1 preset

Verified · 84/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

This Gretsch piggyback amp pairs preamp chassis 6499VR with a 6435 power pack. Two channels, two inputs each, have their own volume, treble and bass; channel 1 adds a three-stage 12AX7 gain section with a gain switch. A 12AX7 spring reverb has intensity and footswitch, and a 6DR7 runs a lamp-driven vibrato with speed and intensity. A 12AX7 inverter drives the power pack: a cathode-biased push-pull pair of 6L6s on a 5U4 rectifier.
