Vox Busker preset

Verified · 87/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Busker is a 1984 solid-state Vox practice amp that runs on battery or mains, chosen by a four-pole rotary switch (two 9-volt pairs or a bridge-rectified mains supply). Two inputs feed a 4558 op-amp stage with a Gain control, then an active Bass, Middle and Treble network and a pair of clipping diodes before the Master volume. A TDA2030 power-amp IC drives the speaker, with a headphone output.

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.
