Gallien-Krueger 2100SEL - Clean preset

Verified · 89/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The 2100SEL is a late-1980s solid-state Gallien-Krueger stereo guitar amp. Channel A has volume with bass, low-mid, high-mid and treble; Channel B adds a gain control and diode clipping ahead of its own four-band EQ and volume. An NE572 compressor can be switched into either channel, and the amp adds noise reduction, built-in chorus and reverb, an effects loop and a resonant power supply, built for the tight, effects-heavy guitar sound of its time.
