Univox also distributed guitars by Matsumoku, effects units by Shin-Ei Companion, and synthesizers by Crumar and Korg.

The Univox Hi-Flier was based loosely on the distinctive Mosrite "reverse swept" shape; it was popularized in the early 1990s by Kurt Cobain, almost two decades after original production had ceased.

Tony Frank, the design engineer at Unicord, created the dual-volume-control two-stage pre-amp that Marshall introduced with their 4140 and 2150 amplifiers, which allowed a "super-dirty" fuzz even at extremely low volumes.

In 1971, Univox introduced the B Group amplifiers, covered in two-toned blue or gray Tolex with distinctive ovaloid cosmetics.
