I have a 1996 Epiphone LP that has one bent tuning peg (happens to be the D string, typically one of two that takes the biggest beating). I actually really like the tuners, so I don't want to replace the rest of them simply because of the one bent one. Surely, plenty of folks HAVE replaced them, though, and so there should be plenty of perfectly good, used tuners floating around in parts drawers? I'm obviously not searching correctly. Help?
