Groove Tubes Soul-O - Clean preset

Close · 79/100 confidence. Most values readable. Minor gaps filled by inference from similar circuits.

The Soul-O 75 is a mid-1990s Groove Tubes amp with two channels, Clean and Mean, switched by photocell (LDR) logic. Each channel has its own gain, treble, bass, mid and volume, with bright switches on Clean and a dark switch on Mean, which adds extra 12AX7 gain stages. A switchable effects loop has send level and wet/dry mix. A 12AX7 long-tail inverter drives a push-pull pair of octal output tubes for 75 watts, with 4, 8 and 16-ohm outputs.
