Mosrite is an American guitar manufacturing company, based in Bakersfield, California, from the late 1950s to the early 1990s. Founded by Semie Moseley, Mosrite guitars were played by many rock and roll and country artists.
Mosrite guitars were known for innovative design, high-quality engineering, very thin, low-fretted and narrow necks, and extremely hot (high output) pickups. Moseley's design for The Ventures, known as the "Ventures Model" (later known as the "Mark I"), was generally considered to be the flagship of the line.
In Bakersfield, Semie Moseley started playing guitar in an evangelical group at age 13. Semie and his brother Andy experimented with guitars from their teen-age years, refinishing instruments and building new necks.
Semie Moseley began building guitars in the Los Angeles area around 1952 or 1953. He began by apprenticing at the Rickenbacker factory, where he learned much of his guitar making skills from Roger Rossmeisl, a German immigrant who brought old-world luthier techniques into the modern electric guitar manufacturing process. One of the most recognizable features on most Mosrite guitars is the "German Carve" on the top that Moseley learned from Rossmeisl. During the same time, Moseley apprenticed with Paul Bigsby in Downey, California, the man who made the first modern solid-body guitar for Merle Travis in 1948, and who invented the Bigsby vibrato tailpiece, which is still used today.
In 1954 Semie built a triple-neck guitar in his garage (the longest neck was a standard guitar, the second-longest neck an octave higher, the shortest was an eight-string mandolin). He presented a double-neck to Joe Maphis, a Los Angeles-area TV performer. By 1956, with an investment from Ray Boatwright, a local Los Angeles minister, Semie and Andy started their company, Mosrite of California. In gratitude to Boatwright, Moseley named the company by combining his and Boatwright's last names; the name is properly pronounced MOZE-rite, based on the pronunciation Semie Moseley used for his own name. Semie, who built guitars for the L.A.-based Rickenbacker company, said to his co-workers that he was making his own product, and he was fired by Rickenbacker.
