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.

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 bought two of these, one Gibson-style and one Fender-style for two of my favorite project guitars, an Epiphone LPX and my Jazz-O-Caster parts guitar. The Gibson was a near drop-in, needing only some trimming and shaping for a perfect fit. The Fender was slightly more challenging, as the neck on the Jazz-O-Caster never saw the inside of any Fender-approved factory! It required a 1/32" shim underneath for a proper fit, and some sanding to make room for the tang. There was a marked increase in the brightness of tone for both instruments, as well as improved intonation. This is MUCH easier than installing a traditional nut, and nearly foolproof IF you follow the instructions. Thanks, Stewart-Macdonald, for stocking such a well-engineered product.
The Zero Glide performs like the manufacturer claims it will. It took less than one hour to complete the installation and have the guitar playing. The nut I removed was cheap plastic and the thin wires had cut down into the nut to the point that there was severe fret buzz on the open strings. The Zero Glide cured that and has all of the strings at the same level. I used a disc sander to shape the nut to length and height in a few minutes. About five more minutes and the nut was polished. The installation looks good. I suggest a person view the manufacturer's installation video before doing the installation.
My old nut was too high. And I didn't want to buy 6 nut files. This Zero glide was much, MUCH cheaper, and it was an easy instal. I taped some 400 grit sandpaper to a plank I had laying around. Sand sand sand, check the fit, repeat. I tried each fret it came with and chose the jumbo. I consider this a major upgrade to my home built super strat.
