My Squier had 2 single coil and a humbucker on the bridge position. The wire going to the back of the guitar seems to be intact and connected. I was tinkering around with it last night and I noticed something. If I put my finger over the wires coming out of the pickup selector switch the humming stops or is at least deadened quite a bit. If I take my finger and tap a string or the bridge (without my figer over these wires) it comes out my amp as a clicking sound. WHen I have my finger over it the clicking stops however there is still a bit of a hum. If anyone has a solution for this that I can do myself without causing more damage that would be great.
