Got a question for you pickup gurus out there. Are there known grounding or phasing issues with 5-string "P-Bass" style pickups since they are split unevenly (ie 3-poles on the top side of the pickup, and 2 poles on the bottom side)?? I've got a 5-String CS Reggie Hamilton that has a lot of hum off the "P" style pickup (2-pole side) when I touch it. If I touch the 3-pole side, no hum. If I complete the ground loop (through my body) by touching the pickup with a finger of my right hand, and the strings on the neck with my left, the hum stops. I thought there may be a bad ground somewhere. I have opened it up and gone over it but can't find any loose or broken grounds (bridge ground is good, etc). Note there is only a single ground coming from the "P" pickup (off the 3-pole side...which does not cause the hum...hum only when I touch the 2-pole side). I hope this makes sense. Thanks.
