Selmer Vanguard preset

verified · 80/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Selmer Vanguard is a small valve combo from Selmer London’s 1960s range. Two input groups each have their own 250K volume and ECC83 triode, mixed into a further ECC83 stage with tone controls. A 6BR8 pentode drives a spring reverb through a transformer, its triode handles recovery, and an ECC83 stage mixes it back with a Depth control and footswitch. An ECC83 inverter drives two cathode-biased 6BW6s into 15 ohms, with an EZ81 rectifier.

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.
