Ceriatone Plexi 100 West Coast Mod - High Treble preset

Verified · 85/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Plexi 100 West Coast Mod is Ceriatone's 100-watt Super Lead-style head fitted with four 6550 power tubes instead of EL34s, giving a tighter, cleaner low end and more headroom than a stock Plexi. It keeps the Normal/Bright Plexi front end with a 12AT7 phase inverter, uses a solid-state rectifier and choke-filtered supply, and adds an effects loop.

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.
