Music Man 2165-RD / 2100-RD - Channel 1 preset

Verified · 80/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The 2165-RD (65 W) and 2100-RD (100 W) are Music Man 'RD' (Reverb/Distortion) amps. An all-op-amp preamp with bright and deep switches and a three-band EQ adds a footswitchable high-gain path with its own Gain and Volume controls. Spring reverb and transistor drivers feed two 6CA7/EL34 output tubes, which suits players who want a clean sound and a lead sound in one amp.

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.
