The Zero Glide Replacement Nut System borrows the "zero fret" concept to reduce string contact in the nut by up to 93%, increasing tuning stability, playability, and open string tone. It only takes a few minutes to install with absolutely no permanent alteration to your instrument. For Classical Guitar.
See the Classical Guitar DelCamp review of the Classical Zero Glide nut.
Also available in Black Delrin.
I put one on my Taylor 12 fret, it made a big improvement in string tone, tuning, and intonation. I'm now going to install them on all my guitars.
Pretty easy to install - sand it down to fit - pick the fret that matches the rest of your fretboard - couldn't be easier!
My third build and first time I used the zero fret, made filing the nut slots easier. The sound is markedly clearer than the other bone nuts I've used.
Great product, Makes a lot of difference in sound and play ability. To say nothing of staying in tune. I put one on a Ovation Legend made in 1972. The guitar always sounded good but was a little tough to play. This made a world of difference. It is now amazing. I have a friend who can't keep his hands off of it. He likes it better than his Rainsong.
