The Garnet Swinger S90 is a 90-watt Canadian tube amplifier head whose name reflected the social optimism of late-1960s youth culture. It shares the core architecture of the Rebel series but was marketed toward younger, style-conscious players rather than established professionals. The Swinger delivered the same capable, full-bodied Canadian tube tone as its Rebel siblings at a comparable price, differing mainly in cosmetics and branding.

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.
