I've got a dead Full-Circle pickup I need to try to repair, which involves removing the bridge and taking the adjuster out. I've gotten instructions for what to try to bring the pickup back to life (subject of another thread if it works), but having never removed the bridge of a bass before, I'm afraid of dropping the soundpost while it's down. I've searched the forum for a home-remedy, but haven't had much luck - most of the posts that reference this subject suggest placing a 25 lb. bag of buckshot over the soundpost to keep it in place while removing the bridge. Seeing as I don't have any 25 lb. bags of buckshot lying around (a shameful thing for any God-fearing Kentucky boy, I know), what are some good homemade substitute options?
