Univox Tube preset

Verified · 80/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

This Univox tube amplifier document covers one of the less common all-tube designs from a brand predominantly known for solid-state products. Univox tube amps from this period reflect the transitional era when manufacturers were moving from tubes to solid-state but still producing tube designs for traditionalist players.

• Years produced: late 1960s–1970s

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.
