Vox VR30 - Clean preset

Verified · 85/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The VR30 is a 30-watt hybrid Vox combo from the mid-2000s. A Clean channel with its own Volume, Treble and Bass sits beside an Overdrive channel with OD Gain, transistor gain stages with diode clipping, its own Treble and Bass and an OD Volume, selected by a footswitchable OD on/off switch. Op-amps drive the spring reverb (Reverb Mix), then a single ECC83 (12AX7) valve stage and a Master Power Level feed an LM3875 power IC.

• Introduced: 2004
• Wattage: 30W
• Channels: 2
• Preamp tubes: 1× 12AX7

Tags: hybrid, reverb, two-channel, mid-wattage.

Schematic-derived preset files for the Neural DSP Quad Cortex and 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.
