The EBow, short for electronic bow or energy bow, is an electronic device used for playing string instruments, most often the electric guitar. It is manufactured by Heet Sound Products, of Los Angeles, California. It was invented by Greg Heet in 1969, introduced in 1976 and patented in 1978.

Bowed guitar is a method of playing a guitar, acoustic or electric, in which the guitarist uses a bow, rather than the more common plectrum, to vibrate the instruments' strings, similar to playing a viola da gamba. Unlike traditionally bowed instruments such as violins, the guitar generally has a relatively flat bridge radius and closely positioned strings, making it difficult to bow individual notes on the middle strings. The technique is often associated with Jimmy Page of Led Zeppelin and the Yardbirds, as well as Jónsi of Sigur Rós. Eddie Phillips of the British group the Creation was one of the first rock guitarists to use a bow in their 1966 song "Making Time".
