Fender Champion 600 Reissue preset

verified · 90/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Champion 600 reissue revives Fender's 1949 Champion 600 student amp in its two-tone cabinet. A 12AX7 with a fixed tone network drives a single cathode-biased 6V6GT in class A on a silicon rectifier, for about 5 watts. It has High and Low inputs and a volume control, and breaks up easily at low volume.

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.
