EVH 5150III 50W - Crunch preset

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

The EVH 5150III 50W is the 2011 half-size version of the three-channel 5150III head. Clean and Crunch share a front end, EQ and volume, while the Lead channel has its own four-stage high-gain path, EQ and volume, with global presence and resonance. A pair of 6L6s gives 50 watts of the big head's tight, saturated voice at lower volume. Eddie Van Halen played every guitar part on "Tattoo" through one.

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.
