Gibson EH-100 (6V6) preset

verified · 90/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

This version of the Gibson EH-100 lap steel and instrument amp has three inputs: one through a 6SQ7 stage and a 500K volume, and two that join after it. A 6C5 gain stage and a 6N7 dual-triode paraphase inverter drive a push-pull pair of 6V6GTs with feedback from the output transformer. A 5Y3 rectifier uses the speaker field coil as its filter choke. There is no tone control.

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.
