Ceriatone 2555 Silver Jubilee preset

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

Ceriatone's 2555 is a hand-built take on Marshall's 100-watt Silver Jubilee head, with three ECC83s and four EL34s. Input gain feeds cascaded stages with a footswitchable channel select between Lead Master and Output Master modes, and a Rhythm Clip switch adds diode clipping, then treble, middle, bass and presence. A pentode/triode switch, series effects loop, bias pot with test jacks and an impedance selector complete it.

Schematic-derived preset files for 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.
