Does anyone have a rough idea on how many hours the batteries will last for side LED's?

I asked Valvil, and he said it can vary, but maybe 15 to 20 hours or so, if I remember right. I may be wrong though. I had accidentally left mine on overnight, and have played about 8 gigs since and they are fine with no sign of going out yet.

just remember to unplug your bass when not playing it, that can drain it's juice.
