Graph Tech nuts, and theit other products, are great!
This nut just didn't do it for me... The thickness isn't right.. it's too narrow.. it wiggles in the nut slot, nut producing a good tight fit..
3,22mm is simply too narrow, and I don't see why Graph Tech makes this nut at that thickness.. Why not go for 3,5, then you had room to slowly sand the thickness down... It's a shame, and I'll have to took for another alternative..
I can't see which other instruments this will fit on?.. Maybe that's just me :-)
Cheers.
