Soldano Hot Mod preset

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

The Soldano Hot Mod is a modification kit developed by Mike Soldano to upgrade amplifiers — particularly Fender and Marshall circuits — with his high-gain preamp topology. It represents the origin of the Soldano gain philosophy, predating the SLO-100, and was used extensively by early 1980s Los Angeles session guitarists and rock players. The Hot Mod is historically significant as the evolutionary predecessor to all Soldano production amplifiers.

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.
