Fender '64 Vibroverb Custom - Normal preset

Verified · 91/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The '64 Vibroverb Custom is Fender's 2002 1×15 recreation of the early blackface Vibroverb. Normal and Vibrato channels each have volume, treble, bass and a bright switch, with spring reverb and an optical vibrato on the Vibrato channel. A Mod switch changes the gain and voicing of the stages, and a rectifier switch chooses the 5AR4 tube rectifier or silicon diodes. A 12AT7 inverter drives a fixed-bias pair of 6L6GCs, rated 40 W RMS into 4 ohms.
