Vox AC30HW preset

Verified · 92/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The AC30HW is the limited hand-wired AC30 that Vox built in England in 2003–04, its last UK-made AC30. It is a single channel with high and low inputs, a Top Boost treble and bass stack, Tone Cut and a master volume, and it swaps the old Vib/Trem channel for valve-driven tremolo and a long-tank spring reverb. Four cathode-biased EL84s run from a GZ34 rectifier through custom transformers on tag-board wiring.

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.
