So I have a series problem. My entire rig gives buzzing feedback.

Every guitar, my amp, Jamup pro on both iphone and ipad with both apogee jam and positive grid plug in, and all my guitar cables are giving me buzzing feedback at all volumes. I've used them through different speakers, and both distorted and clean channels. No combinations of any aforementioned things work to get rid of feedback.

This was not an issue until last night.

Any ideas what could be causing this? Any help and suggestions are appreciated. Thanks
I might've had a similar situation. It was bad grounding in the house I was in at the time. Try it outside and see if the noise stops.
