I have a POD 2.0 and recently the sound became distorted on every setting, regardless of amp model or effect setting. It's a very unattractive fuzzy sound which appeared to come on very suddenly, as though there had been a change in the hardware of the device.

I have isolated the POD as the source of the problem, the guitars and the amp seem to be working fine.

Is there a solution to this problem?

Thanks in advance for any help offered!!
