Marshall Valvestate 10 (8001/8010) - Normal preset

Verified · 82/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Marshall Valvestate series combined a single preamp valve with MOSFET power amplification, delivering affordable multi-channel performance in the 1990s. The hybrid topology gave a warmer response than pure solid-state designs while keeping maintenance and cost low.

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.
