Vox Student V5 preset

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

The Student V5 is a basic three-valve practice amp from the American Vox line that Thomas Organ built in California in the mid-1960s. Two inputs share a 1M Volume control feeding a 12AU6 pentode preamp, which drives a single-ended, cathode-biased 50C5 beam tetrode into a small speaker, with no tone control or negative feedback. A 35W4 half-wave rectifier supplies the high voltage, and the series heaters run from a transformer tap.

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.
