Recorded a song for the side project band Date With Fate and has used an E-bow for some added sound variations. This terrific hand held electronic gadget sounded like a violin and at times sounded like a wind instrument. Borrowed this handy device from a friend and according to him, this was a first generation E-bow. Had a hard time using it, but I got an awesome sustain and a great backwards sound effect.
This gadget works while putting it in front of the string, then as it vibrates, it produces a violin-like sound with a long sustain. It is powered by a 9 volts battery.
