Just tried to replace the stock nut on my Standard 24 with a Graphtec nut. After removing the old nut, it seems as though a fair amount of wood stuck to the old nut, now, neither the old nut or new nut will fit in the slot. I can put the old nut in and the guitar is playable. The nut will either sit flush with the fretboard edge or flush with the neck, but not both. Is this guitar ruined, or will a luthier be able to salvage it?
