what I wanted to know was, how are these bridges different from the Floyd Rose bridges. Also, I want a complete lowdown on tremolos, because I really don't know much about them. What's a 'double locking' tremolo? Are the Edge Pro and Edge Pro II double locking? Is Floyd Rose double locking, for that matter? I need info fast, because I need to buy a guitar quickly, as my relative in the US will leave soon, Thanks a bunch, RK.
