hi, i own a 1991 Ibanez rg 550 and i want to know if the edge pro fits on this guitar (it comes with the original edge) so when the bridge goes bust, i can change it.

Even if it doesn't, it won't be anything a tiny bit of routing and fiddling won't fix. No matter what, if your current bridge breaks, you'll still have TONNES of options.

try to make thread titles that are relevant to the topic at hand. it's warnable to make titles like this.

as long as you know a bit of woodworking, you shouldn't have any real problems.
