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 12 String Guitar (Blank).
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.
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.
I've got a '67 Gretsch Country Gentleman that has what they called the zero fret. I had always wondered why didn't anybody else do this. I put this on my 2010 Gibson Lucille and it solved the nut drag problem. I'm also going to put it on my '76 Les Paul Deluxe. A great solution to an on going problem.
