Jordan Model 120 / 140 preset

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

The Jordan Model 120 and 140 are American solid-state guitar amps built around transistors and an op-amp. Two inputs feed a discrete transistor preamp with bass, treble and volume, followed by a three-position Brite/Normal/Dark switch. An MC1709 op-amp drives MJE2011/MJE2021 output transistors in a push-pull stage on plus and minus 24-volt rails, with a headphone jack. The two models share one circuit at different power ratings.

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.
