Installing a Nut/Cutting Nut Slots
Although PRS offers pre-slotted string nuts for sale, each nut will need to be fine tuned to achieve a proper set up. Sand the bottom side of the nut flat, and then glue the nut into place using superglue. Then, using the correct set of nut slot files, fine tune each slot so that the strings does not bind in the slot. This particular aspect of a set-up can be extremely tricky. If you are unfamiliar with this type of adjustment, it is best to seek the services of a trained guitar technician.
