Hi, i am thinking about buying a pocket pod or a pod 2.0 for use at college and band practise however i am also thinking about putting it through my valveking for more of a range of tones while playing live does anyone have any advice on this or which one would be best.

Hey, I know a guy who has been playing live for years and has been on several tours, and his live effects rig is a Floor POD Plus and a Valveking. I don't remember the exact model of the Valveking, but the tone and overall sound is amazing. Go for it, i'm sure it will turn out great.
Shouldnt hurt. I have a GT-10 runnin through my ValveKing and it sounds a lot better because of it, so it should really improve your tone.
