Park 1231 Vintage L.E. preset

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

The Park 1231 Vintage L.E. is a 20-watt single-channel valve combo from Park, the Marshall-built sister brand. High and low inputs feed an ECC83 gain stage, a passive treble, bass and middle stack and a Volume control, then a second gain stage and an ECC83 long-tail-pair inverter with feedback from the speaker. Two cathode-biased EL84s on a silicon-rectified supply drive a Celestion G12-30, giving early, touch-sensitive breakup.

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.
