Although this doesn't happen all the time, for some odd reason when I change a preset using the footswtches on the POD HD500, the device starts sending out ridiculous feedback every now and then. I know this is not the guitar's fault. Can anybody help me here?
It's happened to me maybe 3-4 times so far over the past 9 months. A bit worrying, but not frequent enough to warrant doing much about it for me. Just need to keep in mind in case you play live, if it happens just switch away again and switch back and it'll be gone.
