Ceriatone JCM102 Double Barrel - Channel 2 preset

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

The JCM102 Double Barrel is a 100-watt Ceriatone head built on a JCM800-style preamp with two footswitchable sets of Gain and Master controls, so one amp gives two JCM800 gain levels. Three ECC83s drive four EL34s, with a shared bass/middle/treble and presence, per-channel bright switches and a post-phase-inverter master.

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.
