Anyone out there have an old Jazz with a warped pickguard? I have a 63, and the guard while not extremely warped is warped on most of the outside edge. Any suggestions on how to flatten it out? I thought of laying a heavy weight on it out in the sun for a short while. (While off the bass of course!) Have any of you guys tried to correct this type of problem with good results? I don't want to make it worse than it already is! Suggestions ?
