Ok one more pickup question. Seems there is alot of knowledge here and I have a guitar with a set of EMG pups in it. They are noisey as hell. I see nothing out of the ordinary and they appear to be wired correctly from the schematics I have found online. It is a hum. If I grab the guitar cable or touch the pickups the hum goes away for the most part. I assume that this is a grounding issue than? Any suggestions on this?
