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. Products Univox amplifiers A number of tube and solid-state amplifiers were produced by Univox over the years. These ranged from small practice combo amps to powerful heads with separate cabinets. Some models had built-in spring reverb and tremolo effects. In 1971 Univox introduced the B Group amplifiers, covered in two-toned blue or gray Tolex with distinctive ovaloid cosmetics. The C-Group (UX) line of amps were used by The Jeff Beck Group and Led Zeppelin. Univox guitars In about 1967 Unicord merged with Merson, an importer of various headstock-brand guitars such as Tempo, Giannini and Hagström. This new company was called "Merson Musical Products, A Division of Unicord Incorporated, A Gulf + Western Systems Company." Around 1968 they started producing Univox-brand guitars. Unicord and Merson split in 1975, but Unicord continued to make Univox guitars until about 1978, even adding some newer models.
