Whelp the noise is back. Friday at the our gig, mid set, my girl looked at me with a look on her face like, what was that noise? After the set she asked me where the static came from and I said I don't know...our drummer was really loud that night and I didn't really even notice...I just wrote it off in my head that it was something affecting the many wireless systems we're running, wireless guitars, wireless vocal mics, wireless in-ears...a lot of potential interference possibilities. Then when I fired the amp up yesterday (at my place, not hers) and it started making that "tuning in an AM radio" sound she said "that's what I heard Friday". I kind of wish something would just let go so it'd be easy to identify the issue. Guess I need to take into someone.
