Bugera 333XL - Lead preset

Verified · 86/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Bugera 333XL is a 120-watt, three-channel tube head from Behringer's Bugera line, aimed at high-gain rock and metal. Clean, Crunch and Lead channels each have their own treble, mid, bass and volume; Crunch and Lead have their own gain and XL switches, with an optical noise gate. A 12AX7 drives a spring reverb, an effects loop has send and return levels, and a 12AX7 long-tail inverter with presence drives four EL34s, with a line out.

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.
