Engl Screamer 50 E330 - Lead preset

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

The Screamer 50 (E330) is ENGL's 50-watt head with relay-switched Clean and Lead channels, each with its own gain and bright switch; the Lead adds a Lo/Hi gain switch and its own volume. The channels share a treble, middle and bass stack, with a spring reverb, a serial effects loop with balance, a switchable lead presence and a master. An ECC83 long-tailed-pair inverter drives a pair of 5881s; the circuit matches the E335.
