"Static" on playback

I’m getting an annoying static sound while playing back my tracks, like an old pin on an old dirty record (how old am I?). There’s no static while I’m recording the tracks and I’m getting frustrated.

Any tips?

Correction, I actually am getting this static any time playing an instrument (guitar). My signal isn’t too strong so not sure what the deal is. Maybe I can figure this out…

Faulty pickup. Bah!
Feeling pretty derpy now.
