Cornford RK100 preset

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

The RK100 is Cornford's 100-watt Richie Kotzen signature head. A single input runs a high-gain triode first stage with a JFET-switched voicing change on a front-panel footswitch, then a dual-gang gain control over two further stages, a cathode follower and a treble, middle and bass stack. A series effects loop and master feed a long-tail inverter with presence, driving four EL34s (6L6 via bias switch), for warm cleans through thick lead.

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.
