(american strat) - My jack was a little lose so I unscrewed the whole thing to lift it up and re-tighten it. When I placed the jack back in the cavity and screwed the pins back in, the cable would not lock in! It goes in as much as you can "slide" in, but when you kinda have to "push" the rest in, it is locked. I've unscrewed it several times and have found that the cable will fit in the jack, just not in the posistion when it's screwed in the guitar like it use to. WHAT DO I DO?!
