Marshall 2098 (1976) - Channel 1 preset

Verified · 84/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The 2098 is a solid-state Marshall from the Unicord US-distribution era, introduced in 1974 as the company's first 100-watt transistor amp; this drawing dates from May 1976. Two channels, each with a FET input stage and volume, mix into a shared tone section with treble, middle, bass, master volume and presence. An echo send and return and a slave output are provided, and MJ3001/MJ2501 Darlington outputs run from ±42-volt rails.

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.
