Vox Berkeley II V1081 preset

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

The Berkeley II V1081 is the solid-state American Vox Berkeley, built by Thomas Organ from 1966 under licence from JMI. Three inputs feed a two-transistor preamp with Bass, Treble and Volume, then a transistor reverb driver, spring delay line and recovery with a Reverb control. A transistor tremolo has Speed and Depth, and a pedal switches tremolo, reverb and a momentary MRB. A transformer-coupled push-pull output drives two 10-inch speakers.

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.
