Impact 60 A S preset

Verified · 85/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Impact 60 A/S was a 60-watt solid-state amplifier variant from the Impact range, distinguished from the standard 60 by a modified channel configuration or switching arrangement. Its circuit was designed for versatility in the club environment, allowing quick changes between clean and driven tones. The A/S designation likely refers to an altered switching or input stage compared to the base model. It served the same working musician market as its sibling models throughout the 1970s.

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.
