E Bow String Driver
The E Bow is a hand-held electronic bow for guitar.
It replaces the pick, letting the guitarist mimic strings, horns, and woodwinds with unbelievable sensitivity. The EBow produces a powerful infinite sustain, rich in harmonics for unique "bowed" guitar sounds. It is one of the most unique "effects" you can buy. Plus you can even use it acoustically!
The E Bow runs on a 9v battery.
