Marshall 1959RR Randy Rhoads preset

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

A limited-edition Marshall tribute to Randy Rhoads, based on the 1959 Super Lead 100-watt head. It keeps the classic two-input, two-volume plexi layout with three ECC83s and four EL34s, and is modified for more gain in the style of Rhoads's own amp. It is aimed at his hot-rodded plexi lead tone.

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.
