Re: Need help picking a Floyd Rose nut width.
R3 is meant to go on bound necks, and it's the standard Jackson width. Problem is, the FR nuts are taller, and not by a little. So you either have to shave down the nut shelf or mill down the nut some for it to work. The Kahler with the built in string retainer works and I'm told that a Gotoh works, but I haven't tried one.
Or you can just buy a Jackson BH43 nut off of ebay.
