Pignose G40V preset

Verified · 93/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Pignose G40V is a tube combo designed by Dennis Kager for Pignose Industries, rated around 40 watts. A single input feeds a 12AX7 gain stage, a Volume control and two more 12AX7 gain stages, then a cathode follower driving a Marshall-style treble, bass and middle stack and a Master. A 12AX7 long-tail-pair inverter with a Presence control in the feedback loop drives two fixed-bias 6L6GCs into 4 or 8 ohms. There is no reverb or effects loop.

• Wattage: 40W
• Channels: 1
• Preamp tubes: 3× 12AX7
• Power tubes: 2× 6L6GC

Tags: clean, crunch, 6l6, mid-wattage.

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.
