Gibson GSS-50 - Normal preset

Close · 72/100 confidence. Most values readable. Minor gaps filled by inference from similar circuits.

The Gibson GSS-50 was a solid-state amp from Gibson's late 1960s transistor lineup, reflecting the industry-wide shift toward solid-state technology during that period. It offered clean, reliable amplification but lacked the warmth of Gibson's tube-based designs.

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.
