They began marketing a line of amplifiers under the name of "Univox". Guitar making operations moved to Japan in 1975 where they continued making guitars until 1982.Production under the Univox name was halted after a fire at the Matsumoku factory.In 1985, Unicord Corporation was purchased by Korg, and the Univox brand was phased out.In the early 1960s the Unicord Corporation, a manufacturer of electric transformers, purchased the Amplifier Corporation of America of Westbury, New York.These are very similar to the earliest Hi Fliers, except that they had a red tortoishell pickguard and truss rod cover, often slimmer neck/body (which became standard for all Hi-Fliers around this time period), and a badge that read, "Univox Custom." In addition, there were Hi-Fliers made that had all the characteristics as the Custom version, but were fitted with a standard "Univox" badge, with no Custom tag.This is likely due to the Hi-Flier Custom being created simply to use leftover stock badges from the previous Univox Custom model (a hollowbody 335-type guitar built in the early 1960s).The Unicord Corporation manufactured electronic transformers. In the early 1960’s when everyone wanted an electric guitar and amplifier, Unicord acquired a Westbury, New York firm called Amplifier Corporation of America.Unicord began production of the Univox amplifiers shortly thereafter.
Semie Mosley was an outstanding luthier and guitar designer, but he was not a good businessman.The factory presumably had many badges left over, and used them up on the Hi-Fliers until they ran out, and resorted back to the standard "Univox" badge.A Phase two Hi-Flier retained the P-90 pickups, and early transitional models also retained the plastic "Univox" headstock badge.About the same time frame that CBS acquired Fender Guitars and Amplifiers, Gulf and Western purchased Unicord and were now in the profitable guitar business. By 1968 Gulf and Western added guitars to their the product line.This was accomplished due to a merger with a Westbury New York company called Merson Musical Products. They distributed Hagstrom guitars from Sweden, Giannini guitars from Brazil and a cheap brand of acoustic guitar called Tempo.
