VHT Standard 12 - Normal preset

Verified · 88/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The VHT Standard 12 is a tweed Deluxe (5E3)-style combo with Normal and Bright channels, each with Hi and Lo inputs, a shared tone control and a cathodyne phase inverter into two 6V6GTs for about 12 watts. Changes from the original circuit include a 12AX7 in V1, local negative feedback on the Bright channel, power tube screen resistors and a headphone jack.

• Wattage: 12W
• Channels: 2
• Preamp tubes: 2× 12AX7
• Power tubes: 2× 6V6GT

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.
