In 1950, Fender introduced the first mass-produced solid-body Spanish-style electric guitar, the Telecaster. Following its success, Fender created the first mass-produced electric bass, the Precision Bass (P-Bass). In 1954, Fender unveiled the Stratocaster (“Strat”) guitar. With the Telecaster and Precision Bass on the market for some time, Leo Fender was able to incorporate input from working musicians into the Stratocaster’s design. The Strat’s comfortable contoured edges and in-built vibrato system led to its soaring popularity.
