I'm in the middle of building a bass out of various parts. The body is brand new with an oil finish and, as such, has no shielding in the control cavity. I'm installing an EMG system (BTS System & PJ pups). I thought I may have read somewhere that EMG systems don't require separate shielding. Can anyone confirm or refute this? I've owned several basses over the years with EMG systems and never bothered to notice if the control cavity was shielded.
