The Fender Stratocaster, often referred to as the Strat, is a model of electric guitar designed by Leo Fender, George Fullerton and Freddie Tavares in 1954, and manufactured continuously to the present. It is a double-cutaway guitar, with an extended top horn for balance while standing. The Stratocaster has been used by many leading guitarists, and thus can be heard on many historic recordings. Along with the Gibson Les Paul, Gibson SG, and the Fender Telecaster, it is one of the most common and enduring models of electric guitar in the world.
