Vox AD100VTH preset

Verified · 84/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The AD100VTH is the 100-watt head version of Vox's AD Valvetronix modeling amps. An op-amp input with normal and high-gain paths feeds a codec and DSP that run the amp models and effects, set by Amp, Gain, Volume, Treble, Middle, Bass and Effects knobs with two channel memories. A 12AX7 Valve Reactor stage, switchable between Class A and AB behaviour, then drives a solid-state power amp with Power Level control and an effects loop.

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.
