Marshall MG250DFX - Overdrive preset

Verified · 88/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The MG250DFX is a solid-state stereo combo from Marshall's early-2000s MG series. Footswitchable Clean and Overdrive channels each have their own gain, EQ and volume, with LED clipping and a Contour control on the Overdrive side. A digital effects card with reverb and effects levels, a CD input, a stereo effects loop and a headphone output feed separate left and right TDA7293 power amps driving two speaker outputs.

• Channels: 2

Tags: solid-state, stereo, crunch, two-channel.

Schematic-derived preset files for the Neural DSP Quad Cortex and 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.
