Ceriatone Plexi 100 Super Bass - Normal preset

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

The Plexi 100 Super Bass is Ceriatone's reproduction of the 1968-style Marshall 100-watt Super Bass head, with four fixed-bias EL34s and independently volumed Normal and Bright channels. The bass-model voicing gives a rounder, less bright character than the Super Lead while keeping the Plexi Presence/Bass/Middle/Treble stack and adding 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.
