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 (For Taylor Guitars).
Also available in Black Delrin.
One for Fender Telecaster, the other for Breedlove acoustic. Both of these guitars are top 10 instruments. The Zero Glide nut improvement came through as described on Youtube demos. So much better string action (lower with out any fret buzz) Clarity in open string tone chords and pulloff plucking, faster tuning to pitch, using electronic tuner, remaining in pitch once strings stretch has settled in. I took my time to install on both guitars about 2 hours for each instrument. Have new custom Guitar that I will 99% sure I will add this improvement to soon. I see this becoming a standard upgrade to many popular manufactures. Lastly the sustain in open chords on all strings cant be described.
The bone nut was easy to install. I sanded the length and depth with a table sander. The instructions are complete and easy to follow. Four zero frets of different sizes are included in the banjo kit--you try the smallest and work your way up until you have no open string buzz. Use medium viscosity cyanoacrylate (available from Stewmac) so you have time to set the nut and fret properly. I'm pleased with the results, improved tone, and hammer-ons and pull-offs are more defined.
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.
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.
