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

This G-60 is the 1987 solid-state 60-watt guitar amp from Ampeg's Vector Series under St. Louis Music, unrelated to the 1970s G-60 apart from the name. It has a two-channel op-amp and JFET preamp with clean and lead channels feeding a transistor power amp. It was a dependable, affordable channel-switching amp for gigging guitarists of the late 1980s.

Schematic-derived preset files for the Neural DSP Quad Cortex and 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.
