Ceriatone FAS 100 - OD preset

Verified · 84/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The FAS 100 is a 100-watt, two-channel Ceriatone head with four 6L6GCs on a solid-state rectifier. Normal and OD channels each have their own volume and master and are relay-switched, sharing bass, middle and treble plus presence and depth. Normal adds a Clean/Crunch switch and a clean bright switch, OD a three-way bright switch. Two effects loops, a slave out with level and a 4/8/16-ohm selector, for modern clean through tight high gain.

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.
