Mesa Boogie Heartbreaker - Channel 1 preset

Verified · 91/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Heartbreaker is a 100-watt two-channel Mesa/Boogie voiced for clean and pushed tones rather than extreme gain. Each channel has a Hi/Lo gain switch and its own volume, treble, middle, bass, master, reverb and presence; channel 1 puts its tone stack before the gain stages, channel 2 after. Valve reverb and an effects loop feed four 6L6s (EL34 option) with Bold/Curve feedback, a 100/60-watt switch and a 5AR4 or diode rectifier choice.
