Peavey Butcher preset

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

The Peavey Butcher is a mid-1980s all-valve head built for high-gain rock and metal. High and low gain inputs feed three 12AX7s, with Pre and Post gain controls around a Low, Mid and High tone stack, then a long-tailed-pair phase inverter with a Presence control in the feedback loop. Four 6L6GCs with fixed bias drive outputs for 4, 8 and 16 ohm cabinets, and a booster output jack sits on the control panel.

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.
