Fender 30 - Lead preset

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

The Fender Thirty is an early-1980s 30-watt two-channel tube combo from the same series as the Seventy Five and 140. The Normal channel has treble, bass and volume with a bright switch. The Reverb channel adds a middle control, a mid boost switch and a preamp gain control with pull switches for extra gain, plus spring reverb driven by a 12AT7. Channels switch by LDR from the panel or a footswitch, and a 12AT7 inverter drives a pair of fixed-bias 6L6GCs from a 5U4GB valve rectifier, with a line out.
