I have an Ibanez RG Premium RG921QMF guitar that comes with the Tight End R fixed bridge. I see there is another version of the same guitar that would come with a tremolo Edge Zero II bridge. I'm thinking if it isn't too big a deal, I might swap bridges. I see a couple Edge Zero II bridges for about $100. If it is a direct swap and doesn't require cutting or too much drilling, I might make the change. Is it something I can do, having never worked on a guitar before or should I bring it to someone?
