Carvin X-100A - Rhythm preset

Verified · 83/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The X-100 is Carvin's 1981 X-series tube guitar head, with four 6L6GCs for 100 watts; the X-30 and X-60 used fewer output tubes. Two 12AX7s give a clean path with volume, bright, treble, bass and mid, and a relay-switched Lead path with its own drive and master. A solid-state five-band graphic EQ, footswitchable volume boost and reverb follow, and a 12AX7 inverter with presence drives the output stage, with a 60% power switch and slave out.
