Was watching a video for The Reign of Kindo's song October's Storm:

My question is, does anyone know what the guitarist uses at 1:02, with the blue light? Love the sound it produces...is it for sustain? Can it be used on a bass? Thanks in advance

That's called "e-bow"

It can be used on bass. It creates a magnetic field in the string and it provides infinite sustain..Michal Manring uses it a lot

Thank you! Very cool...I hadn't seen this before. I'd love to try one out on bass.
