Hello. I am having an issue with my xt live. For example if I am on the line 6 clean preset while playing it will randomly have an overdrive sound to it like I stepped on a distortion pedal or cranked up the gain. It doesn't last long, like a flicker of overdrive and then back to the clean sound. I have tried different guitars and cables but it is still doing this so I am sure its the xt live. Any suggestions? Thank you!
