I have a Floyd Rose tremolo on my Ibanez RG 270. There is some thing that goes on the bar where it connects to the bridge. I think I need that. All's I know is there is a giant hole where the bar would go. I can almost slide my pinky into the hole, it's so big. It's just a hole, and that's it. What do I need to get to start whammin' again? Help me out here.
