I've had this pod for 6 years.

Suddenly, every patch has distortion on it, and no matter how low I set all the inputs (guitar, output, chan volume) or having all of the stompboxes/amp sims off or on.... I get distortion, and the clip signal goes haywire. I've tried multiple guitars, output modes, patch cords... but same effect. Clip signal even on tiny volumes.

I reinstalled the flash and firmware returning to factory defaults... nothing.  I updated all the drivers in monkey and then the Pod... nothing.

any ideas?

i can send you an audio clip of the sound if that gives you any clues. Tell me where to email. .Just to narrow down the problem for you: This is not computer recording related. I play it through my effects loop in my amp (havnt changed guitars/amps in years) but it also is duplicated when I plug it into the computer.thanks a bundle!
