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.
Had tuning stability and buzzing issues after ten years on my first bone nut. Also have always been bothered by open string vs. fretted string sounds. I play mostly flat picking/crosspicking styles and Travis style picking. The consistency of the note makes both more enjoyable for me. No buzzing lower action smoother tuning smoother playing easier bending etc... Have all been a result. Took me about two hours to get height and width of nut and fret correct. Had to get a smaller get shipped from gold tone and their customer service was the easiest I have ever experienced. Had part in two days and I am satisfied.
Just put one of these on an old beater of a cheap strat-clone kit that I use to experiment with "creative" wiring. Suddenly its in tune up and down the neck and stays that way after using the trem as well. It cost half the price of the kit but it has significantly improved the value of the instrument to me. It required a little sanding of the back of the nut but nothing drastic. I dont have many dedicated luthier tools so the fret wire is not trimmed perfectly (but the look is in keeping with the overall "relic'd" appearance of the guitar). The question now becomes can I get a discount if I order these in bulk?
The ZerO Glide Nuts are everything they say they are,.. and more. I just started playing guitar about 3 years ago, but I've worked with wood and restoring antiques all my life, so those skills and knowledge have been bleeding over into guitar maintenance.
This so to speak, was my first nut job. But the idea was clear from the start - remove & replace. Now the guitar nobody thought was worth fixing, is playing hotter than it ever was. Many thanks to StewMac for suppling quality from and for craftsmen.
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.
