I assembled a Warmoth strat a while back. Right now I have a Wilkinson tremelo that is set up to float 1/8" above the body. I'd like to get a Callaham bridge, but when I first assembled the guitar I had the tremelo flush with the body, and the neck was too high and the strings touched the frets up high near the body. I couldn't raise the saddles high enough to get the action I wanted. I know I can add a shim at the front of the neck pocket, but I'd prefer not to. Do I have any other alternatives? I was thinking of sanding the heel of the neck. Is that a bad idea? Will I have to refinish the area I sand to prevent moisture from getting in the neck?
