Mailist to discuss all issues regarding the Digitech GSP-2101 Guitar FX Processor

I recently tried using my 2101 after a long period in storage. When I turned it on, everything started as usual but the only sound I got was this horrible static and crackling. I could hear the effect in the background when I didn't play anything (swishing of phasers, tremolos, etc) but I couldn't get any real sound if I played. If I put the unit in bypass everything was fine, no more cracking. If I run the FX send to my amp same thing, no cracking. So it is clearly the digital section. Is there any thing I can do or am I SOL? Thanks.
