Univox Lafayette U-80A preset

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

The Lafayette U-80A is a small Univox-built tube combo with Guitar, Accordion and Aux inputs, a single volume and tone control, and a pair of 6AQ5s in fixed bias. It uses an unusual floating-paraphase inverter and bias-modulating tremolo with a footswitch.

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.
