Ceriatone Lightning Lunchbox preset

Verified · 84/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Lightning Lunchbox is Ceriatone's compact head inspired by the Matchless Lightning. A single channel runs a volume with a three-way bright switch into bass and treble, then a master with a defeat switch. Three ECC83s drive two cathode-biased EL84s from a GZ34 rectifier, with a half-power switch, line out and impedance selector. It gives the chimey, harmonically rich EL84 clean and touch-sensitive breakup of that design.

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.
