Re: Floyd Rose specifications
If you mean that you want to use an OFR nut with your new OFR, bear in mind that neither the bridge nor the new nut will match the radius of the fretboard. You'll need to shim the saddles to get the bridge to match, and you'll probably be best off keeping the stock nut to get it to match up there.
If you're insistent on changing the nut, I know Rich is backordered at the moment, you might have some trouble getting hold of an ibanez locking nut. If you end up using the floyd one, then you'll have to alter the depth of the nut slots somehow, and thats a hell of a project.
