Kustom '72 Coupe - Clean preset

Verified · 86/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The '72 Coupe is an all-tube two-channel head from Kustom's revived Coupe line. Clean and Lead channels each have their own volume and master, and switching is relay-driven. Op-amps handle the reverb, and there is an XLR direct out. Four 12AX7s feed four fixed-bias output tubes that accept either 6L6 or EL34, with an impedance selector, so players can choose between an American or a British power-section voice.

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.
