Marshall 8008 Power Amp preset

Verified · 90/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The 8008 is a 2x80-watt stereo solid-state rack power amp from 1992, built to follow Marshall's rack preamps such as the JMP-1. Channel A and Channel B each have their own input and Gain control, a TL072 input stage and a discrete complementary output stage with BDV64/BDV65 Darlington transistors. An Output Power Mode switch selects current or voltage drive for a more valve-like feel. It has no tone controls.

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.
