Marshall JCM2000 TSL60 - Lead preset

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

The JCM2000 TSL60 is the 60-watt version of Marshall's Triple Super Lead head, from around 1999. Clean, Crunch and Lead channels are relay-switched around four ECC83s, the last a long-tail phase inverter driving a fixed-bias pair of EL34s. An op-amp section adds spring reverb, a switchable-level effects loop and a balanced XLR emulated DI output. It is a smaller-power sibling of the TSL100.

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.
