Vox AD120VT preset

Verified · 86/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The AD120VT is a stereo Valvetronix modeling combo rated at 120 watts (2 × 60 W). Hi and Lo inputs feed a DSP that runs the amp models and effects, with programmable channel memories. Each side of the stereo signal then passes its own 12AX7 Valve Reactor stage before a solid-state Class AB power amp, so the valves shape the power-amp response rather than amplify to the speakers. A stereo effects loop and line/phones outputs are provided.

Tags: hybrid, stereo, high-wattage, modern.

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.
