I started having serious volume loss when using the neck pickup on my guitar. Taking it apart, there was some solder connecting the lug for the neck pup to metal housing of the switch and shorting it out. I tried to clean it up, but there's a small gap between the board and the metal housing, and it's just so hard to get out. I'm not sure if it's possible to take it apart, but I'm pretty sure I could take care of it if I could. Here's what the switch looks like.

I tried bending those four clips closed, and it seemed to loosen it up, sort of. Do I need to desolder all the lugs from the back of the board?
