Selmer Truvoice 12/T preset

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

The TruVoice 12/T is a small valve combo from Selmer London’s Truvoice range, shown on a clean modern redraw. Two inputs feed a cascaded ECC83 preamp with Volume and Tone controls. A second ECC83 splits duty: one triode is a cathodyne phase inverter, the other a tremolo oscillator with Depth, Speed and a footswitch. A push-pull pair of cathode-biased 6AQ5s drives the speaker, with an EZ80 rectifier and an oil-filled filter capacitor.

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.
