The guys at my local store say there should be two pieces that fit into the sides of the jazzmaster/jaguar bridge to keep it held in the bridge plate. But, the person I bought the guitar from says that the bridge is just supposed to be held in with string tension, and I've also looked at lots of different pictures of these bridges and don't really see anything fit in the two holes in the side. So, are these bridges held in by just string tension or what?
By the way, my bridge isn't on a jaguar/jazzmaster, it's on a telecaster with a bigsby installed. does that make any difference as to how the bridge is supposed to be held in?
