Verified · 88/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Cornford MK50H II is a 50-watt two-channel head with Clean and Lead channels switched by JFETs and relays, each with its own master volume through the effects loop. The output stage takes two EL34s or 6L6s via a switch, and a front-panel boost adds gain, giving a range from clean to saturated British 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.
