Ceriatone Plexi 50 Bass - Bright preset

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

Ceriatone's Plexi 50 Bass follows the late-'60s Marshall 50-watt bass-model head: EL34 power, Normal and Bright input channels that can be jumpered, and the classic Plexi Presence/Bass/Middle/Treble stack. It gives the raw, open Plexi crunch at a more manageable volume than a 100-watt head.

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.
