http://i303.photobucket.com/albums/nn154/mvd18969/cx592225.jpg I picked up a prewired Mighty Mite pickguard to put in a Charvel Model 3 that I grabbed a few months back. From the picture, you can see it is a humbucker in the bridge w/ dual "hot rails" style single coils in mid and neck. It has a 5-way selector switch. When I got it, a friend helped me install and commented on how well made and shielded the unit was. The tone that I get from all of the pickups is awesome. Very seymour duncan-esque at a fraction of the price. The problem I am having is with the selector switch in full bridge position. there seems to be a loud hum w/ the humbucker where any of the other pickup configs are quiet as a mouse. I checked all the grounding and tried a jumper from the spring claw to the bridge w/ no success. Any ideas???? The unit is brand new and I have no idea what causing this.
