I have a 61 SG ressiue and when I put the pickup switch in the middle and try to adjust the volume on the neck down both the bridge and neck go down, same thing happens if I try to lower the bridge volume. Is their a diagram to change this so I can adjust the volume on the bridge or neck without affecting the other. I'm going to switch pickups out with rio grande BBQ's, so changeing the wireing shouldnt be to big of a deal.?.. :?
