Laney GC30V - Drive preset

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

The GC30V is a mid-1990s Laney all-valve 30-watt combo powered by four cathode-biased EL84s. A relay-switched Clean channel with a bright switch and a Drive channel with its own gain and volume share treble, bass and middle controls, and three ECC83s handle the preamp and phase inverter. It adds spring reverb and an effects loop with level control, plus 4- and 8-ohm outputs.
