I've had my DigiTech Grunge Pad for about 9 months, and every single day it's worked perfectly. The day I decide to take it to school, it quits working .

I think it shorted out...the signal just stops at the grunge pad. If you plug straight into the amp it works, but whenever you include the pad you get nothing, not even a clean channel.

Any suggestions as to what the problem is, and what I might do to fix it?
uhh....check batterie, cable (both from guitar to grunge, and from grung to amp)
my grunge pedal never did that... when you plug it in, does the lil red light turn on? if it doesnt then you know its a power problem, not a cable prob.
