You've only had it a couple of months so it is well within warranty, get a replacement unit not a repair, otherwise you'll have to wait for shipping both ways plus repair time.
The shock thing could be many things: I imagine it is your system (bad wiring in cables, guitar, mic) or more seriously possibly your home's wiring is bad. Get a replacement Pod first and see if you still have the same trouble.
