Tech's notes: "Replacement nuts and saddles typically measure slightly larger than necessary to ensure a tight fit. The extra material is easily shaped down with fine grit sandpaper. The most important thing to check is that the string spacing is a close match to your existing nut. If pre-slotted, you should also have a tech make sure the slots are cut correctly for your particular string gauge and fingerboard radius."
