Mesa Boogie F-30 - Lead preset

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

The F-30 is a two-channel 30-watt Mesa/Boogie combo from the F-series of the early 2000s. Channel 1 and channel 2 each have their own gain, treble, middle, bass, reverb level and master, with the lead channel adding a cascaded 12AX7 gain stage. An op-amp-driven spring reverb, a graphic EQ section, an effects loop with mix level and a record/headphone output follow, and a 12AX7 phase inverter drives two fixed-bias EL84s from a solid-state supply.
