The Osborne guitar Company was established in the mid 1970s by jazz guitarist Mary Osborne and her husband Ralph Scaffidi, a jazz trumpeter. Scaffidi had previously worked as a sales rep for Mosrite and also founded his own company,  Rosac Electronics which made fuzz pedals. The Osborne Guitar Company was founded to make solidbody electric guitars and basses. They hired experienced guitar builders and Mary Osborne was involved with the design of the instruments. They had trouble breaking into the electric guitar market so Scaffidi took a new direction and focused on making amplifiers and PA systems and the company became Osborne Sound Laboratories.
