Trace Elliot Bonneville preset

verified · 86/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Bonneville was Trace Elliot's mid-1990s all-valve guitar amp, sold as the H100 head with four EL34s and the C50 combo with two. A single channel runs an ECC83 cascade with a relay-switched gain boost, bright switch, treble, middle, bass and presence, then two footswitchable master volumes. The effects loop is valve-buffered and switches series or parallel, the combo adds spring reverb, and an ECC83 long-tail inverter drives fixed-bias EL34s.

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.
