With my POD Go, I get this high pitched squealing feedback through my studio monitors or a PA if I stand to close to the speakers. The sound is like microphonic feedback, but I know it isn’t that because I made sure all my pickups were wax-potted. It happens no matter what guitar I’m using. I’ve tried my guitars through regular amps and it’s fine.
When my guitar is unplugged, if I point the cable at the speaker it squeals just the same.
I have suspected it may be due to the pickup magnet inductively coupling with the tweeter magnet (Cliff from Fractal Audio talks about this phenomenon on the AxeFx wiki) but at the same time, I’ve tried using a regular cab instead of a frfr style monitor and it still happened. The only other thing I could maybe think of is my power cable is frayed a little bit.
any ideas on how to fix this issue?
