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.
works like a charm for the stuff I do at weekend gigs,from flutter trem to dive whammy , but most of all, I no longer hear that creaking sound by the nut when using my tremolo and it stays in tune well along with my Wilkinson VSVG Tremolo.
Easy to install for me cause I work for two guitar shops on a on/off basis and am use to making bone nuts from scratch,so if you've never done guitar nut work before I suggest taking it to a well trusted guitar shop with a good tech. It does take patience if you want it to look like a pro and function the way its suppose to. Highly recommend it along with a Wilkinson VSVG and a high gear ratio tuners.. Be buying more soon for my other guitars....
Just got a second one. Used the first on a Tele build. The multiple heights included give plenty of options. Takes some tweaking but so does a standard nut and you don't have to worry about overdoing anything.
An inexperienced guitar tech worked on the nut of my Guild M75 Aristocrat electric and I ended up with a "sitar" sound on my high E string and a dead G string and bad intonation. A friend recommended Zero Glide and that company recommended this particular nut.
Installation was not particularly difficult for a handy guy, but took two hours and involved sanding nearly 1/8 inch off the bottom of the new nut and 1/16th plus off each side while being careful to keep it even. The video on the company website helps. Once fitted correctly you decide how big of a 'zero fret' you want. There are four of different sizes in the package. I tried them all and found that the smaller ones provide very low action at the nut (which is nice), but require a higher action up the neck to clear the first fret where the strings can rattle. I ended up using the largest fret provided as it allowed me low action where I need it. Once you have it figured out you trim the zero fret to length and glue it
