Marshall Super 100 JH preset

Verified · 92/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

A hand-wired Marshall reissue of the 1960s Super 100 as used by Jimi Hendrix. Normal and High Treble inputs with their own volumes feed three ECC83s, and four KT66s produce 100 watts from a diode rectifier. It recreates the loud, open, early-plexi tone of that era.

Schematic-derived preset files for 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.
