Music Man 2100-150 - Bass preset

Verified · 92/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The 2100-150 is a 150-watt Music Man head with Normal and Bass channels. Each channel has an op-amp input stage and a passive treble/bass/midrange stack, followed by a soft limiter, master volume and Deep switch. An op-amp phase splitter and driver transistors cathode-drive four 6L6GC output tubes at about 700 V. There are no preamp tubes.

Schematic-derived preset files for the Neural DSP Quad Cortex and 16 Fractal and Line 6 modelers: Axe-Fx II/XL/XL+, Axe-Fx III, FM3, FM9, and the full Helix family (Floor, LT, Rack, HX Stomp, HX Stomp XL, Native).

Gridleak extracts amp parameters from original circuit schematics using AI vision — component values, gain staging, tone stack topology, tube types — then generates native preset files for every supported modeler. Every extraction is scored 0–100 and the score is published.
