Orange OR50 preset

Verified · 80/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The OR50 is an Orange tube head with a single channel. It has two 12AX7 gain stages with bright switches, a treble/mid/bass EQ and a master volume, driving a pair of EL34s. A switch selects Class A at 30 W or Class AB at 50 W. It is voiced for thick, saturated British crunch and lead tones.

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.
