Semie Moseley’s first job at Rickenbacker ended abruptly in 1955, when he was fired for building his own guitar in their factory. The event prompted him to start his own company with Reverend Ray Boatright, an evangelical minister. They combined their names to produce that of the new company, Mosrite. At first the business consisted mostly of custom-built instruments, but after adding other business partners, particularly the rock group, The Ventures, in the 1960s, the company expanded and was building up to 300 guitars a month. Mass production ended in 1969, when the factory closed, but Moseley continued to build custom guitars through the 1970s and '80s.

Barbara Mandrell and Semie Moseley (1935-1992) had worked together since the beginning of her career. Her first record was on Moseley’s Mosrite record label. This album, which made it on the Billboard Charts, was recorded when she was only seventeen.

Barbara Mandrell played her then brand-new, electric double-neck guitar in the live recording of her 1981 album, Barbara Mandrell Live, performed in the Roy Acuff Theater at Opryland, U.S.A. Other instruments played on this album by the multi-talented musician include the banjo, dobro, mandolin, lap steel guitar, and saxophone. Musicians collaborating with Mandrell on this recording included her band, "The Do-Rites."

The initial, M., along with the maker's signature, Made By / Semie / Moseley / 1981, appear on the peghead of the longer neck.
