Now that I have my custom 22, I want to put schaller strap locks on it so I won't drop it. I didn't have this trouble on the tremonti but when I tried to install the buttons on the guitar the screws from the prs buttons would not sink down inside. The heads of the screws are too wide and the screws that came with the schallers seem to be too small to sink in stripping some wood or pop out. Is there anything I can do to install these puppies? I appreciate any advice.
