So I moved into a new apartment about a week ago, and while I've been too busy to record any new music, I have noticed something that's going to be a problem. My electric guitar is picking up really bad interference (like the hum you get when you sit close to a monitor), except I get it anywhere and everywhere in the apartment, no matter which way I face. I've never had a problem with the guitar before so I don't think it's a grounding issue in the guitar itself. Even running all my equipment through a power conditioner doesn't help. I guess it could be all the electronics and routers in this building, but I'm not sure. I can make do for clean sounds, but the moment I add any gain, then hum comes in at a noticeable level. Kinda makes it hard to record
Any ideas on some solutions, or is there a way I can remove this hum post recording without totally screwing the quality?
