Contributing greatly to Fullerton's musical heritage was the Fender musical instrument company, whose products such as the Stratocaster and Telecaster electric guitars, Precision Bass bass guitar, and Twin Reverb guitar amplifier revolutionized the music business and contributed greatly to the development of rock and roll. Leo Fender sold the company to CBS in 1965; production continued in the Fullerton plant until 1985, when the then-ruined company was sold to a group of private investors. (It was later reconstituted as Fender Musical Instrument Corporation, with its major production facilities in neighboring Corona and across the US-Mexico border in Ensenada, Baja California, and its headquarters in Scottsdale, Arizona.) In 1980, Leo Fender and his original partner George Fullerton (relation to the Fullerton founder of the same name unknown) reunited and started a new company, G&L (George and Leo) Guitars, which are built in what had been Leo Fender's CLF Research factory in Fullerton.
