Marshall 6100 30th Anniversary - Lead preset

Verified · 87/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The 6100 head and 6101 combo were built for Marshall's 30th anniversary in 1992. Three channels (Clean, Crunch and Lead) share six ECC83s in the preamp, with MIDI patch memory, footswitching, low-volume compensation and a series/parallel effects loop. An ECC83 long-tail inverter drives four 5881s with a high/low output power switch and a triode/pentode switch, plus a speaker-compensated balanced XLR output.

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.
