My Epiphone LP does not seem to want to stay in tune, no matter what I do. I checked out the stop bar and there is a 1/4 inch space between the body of the guitar and the bottom of the stop bar stud on both sides at the rear. This tells me that it's allowing the stop bar to lean forward which may be the problem. Has anyone encountered this problem, and what's the fix?
