Marshall JCM2000 DSL201 - Ultra Gain preset

Verified · 86/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The JCM2000 DSL201 is the 20-watt combo of Marshall's Dual Super Lead series from the late 1990s, with relay-switched Classic and Ultra gain channels, op-amp-driven spring reverb and an effects loop. Three ECC83 gain stages and an ECC83 phase inverter drive a pair of EL84s rather than the EL34s of the DSL heads, giving a brighter, more compressed version of the DSL voice at club volumes.

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.
