E-Bow

An E-Bow is a hand-held device used to create the effect of bowing on an electric guitar string. The earliest examples only worked on the low E string, but today the E-Bow works on any string. The E-Bow is powered by a 9-volt battery and produces a magnetic field that sets the string it’s held over into motion without having to pluck it. The unit is fairly easy to use, but developing a technique for moving between different strings requires practice.
