Vox AC100CPH - Channel 2 preset

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

The AC100CPH is a 2007-era 100-watt Vox head with four EL34s in Class AB and four ECC83s, the last as phase splitter. Channel 1 has Gain, Treble, Middle, Bass, Tone Cut and Volume; Channel 2 has Gain with Fat and Bright switches, Treble, Middle, Bass, Volume and Presence.

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.
