The Ebow (ee-baw) or electronic bow (also sometimes referred to as an “energy bow”) is a hand-held device used to augment the sound of a guitar as it’s played. With an ebow, the strings are played with an electromagnetic field. This is done in the place of picking the strings with fingers or a guitar pick. The electromagnetic field created by the ebow creates a continuous unique tone, which is unlike any other sound that could normally be created by playing a guitar. The sound and tone the ebow creates can be changed by altering the linear direction of the device on the string, which changes the string harmonics.
