Ceriatone Overtone Special FM 50 - Overdrive preset

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

The OTS Ford Mustang 50 is Ceriatone's 50-watt take on the Dumble Overdrive Special. A JFET input buffer feeds three ECC83s: a volume into treble, middle and bass with Rock/Jazz, Mid-Boost and Bright switches, then a relay-switched overdrive with ratio and level, a master and presence. Two 6L6GCs on a solid-state rectifier, a low-feedback switch, footswitched OD and PAB, OD trim, preamp out/power amp in and a half-power switch.

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.
