Vox AC2/30 - Channel 1 preset

Verified · 88/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The AC2/30 is the first 30-watt Vox amp, from around 1958, and an ancestor of the AC30. Two input pairs each have a 12AU7 triode and their own volume, sharing bass and treble controls. A 12AU7 phase inverter drives two EL34s with adjustable fixed bias, on a GZ34 rectifier, into a 15 ohm speaker jack. An octal output socket powers a radio tuner or the Vibravox unit.

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.
