I recently put a hipshot D-tuner/bass Xtender key on my Musicman Stingray bass. It was very easy to install and I'm very pleased with it. However, I do have a question and concern about the phillips head screw which holds the wheel gear and post in place. If I tighten it fully then the D-tuner doesn't work. If I keep it a little looser, then won't it eventually loosen and not keep acurate tune? How about putting a little Lock Tite on the screw? Would that help? Anyone out there experience the same thing? Any help or advice would be greatly appreciated? Thanks!!!
