Univox U-150RX preset

Verified · 91/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The U-150RX is a solid-state Univox combo of 1971, built by Unicord. Guitar, Mic and Organ inputs feed a single transistor stage with volume, treble and bass controls, then a transformer-coupled germanium output pair on a 36 V supply driving two speakers. A transistor reverb driver and recovery stage feed a spring line with a level control and footswitch, and a transistor tremolo oscillator offers speed, intensity and 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.
