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

The Vibroverb 6G16 is Fender's first combo with built-in reverb, made in brown Tolex in 1963. Normal and Bright channels each have two inputs and their own volume, treble and bass. The Bright channel feeds a spring reverb driven by a 12AX7 with a 7025 recovery stage and a footswitch, and a 12AX7 oscillator varies the output valves' bias for vibrato with speed and intensity. A 7025 long-tail inverter drives two 6L6GCs on a GZ34 rectifier.
