Hughes & Kettner ATS 120 - Crunch preset

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

The ATS 120 is a hybrid Hughes & Kettner combo from the early 1990s: a tube preamp driving a solid-state MOSFET power amp rated at 120 watts. Its Crunch and Lead (overdrive) channels run through two ECC83 stages, while the Clean channel, reverb and effects loop are handled by solid-state circuitry. It pairs tube-driven gain with a lightweight, low-maintenance power section.

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.
