The Fender Telecaster, colloquially known as the Tele, is an electric guitar produced by Fender. Together with its sister model the Esquire, it was the world's first mass-produced, commercially successful solid-body electric guitar. Its simple yet effective design and revolutionary sound broke ground and set trends in electric guitar manufacturing and popular music. Many prominent rock musicians have been associated with the Telecaster for use in studio recording and live performances, most notably Bruce Springsteen, Luis Alberto Spinetta, Keith Richards and George Harrison.

An electric guitar is a guitar that requires external amplification in order to be heard at typical performance volumes, unlike a standard acoustic guitar. It uses one or more pickups to convert the vibration of its strings into electrical signals, which ultimately are reproduced as sound by loudspeakers. The sound is sometimes shaped or electronically altered to achieve different timbres or tonal qualities from that of an acoustic guitar via amplifier settings or knobs on the guitar. Often, this is done through the use of effects such as reverb, distortion and "overdrive"; the latter is considered to be a key element of electric blues guitar music and jazz, rock and heavy-metal guitar-playing. Designs also exist combining attributes of the electric and acoustic guitars: the semi-acoustic and acoustic-electric guitars.
