I have a Line 6 PODxt Live effects unit for guitar that I use frequently and it's great. Does anyone know if I can use if safely for bass also? I know the new POD X3 is for both guitar and bass but I only recently bought my xt and don't want to get a new unit. It would be great if I could use it for my bass too. I don't need it for much....just some overdrive really, but it would save me having to shell out for a whole new unit. Thanx.
