Fender Vibrolux 6G11-A - Bright preset

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

The Vibrolux 6G11-A is a revision of the brown-era Vibrolux with Normal and Bright channels, each with two inputs and its own volume, treble and bass. A 12AX7 oscillator with speed and intensity controls and a footpedal jack varies the output valves' bias for its tremolo, and a 12AX7 long-tail phase inverter drives two 6L6GCs on a GZ34 rectifier.
