Peavey Roadmaster - Normal preset

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

The Peavey Road Master is a 1983 all-tube head with two LDR-switched channels. The Normal channel has Pre (pull bright), Low, Mid and High (pull thick) and Post (pull select); the Lead channel has Pre (pull bright), a Pump gain control, its own Low, Mid and High (pull thick) and Post (pull smooth). A 12AT7 drives the spring reverb, and a 12AX7 long-tail-pair inverter with Presence feeds a 12AT7 driver stage and six fixed-bias 6L6GCs.

Schematic-derived preset files for 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.
