Graphtech nuts

[Grassie]

What’s the deal with these? They have a curved base rather than a flat one, in my experience all nut slots are cut flat, so has anyone used these and had to fettle either the nut or slot to get it to fit?

Fenders generally have a curved slot, so need a curved nut; most other brands use a flat slot. Some Graph-techs (although no bass ones I could see) come with a curved base with a little nubbin in the middle so they fit flat slots too. They have loads of versions so make sure to get the right one.
