Product Description

The Ultimate Nut Solution

The Zero Glide Nut System improves upon the "zero-fret" concept by combining a specially-made nickel-silver fret with a patented bone nut that’s designed for fitting into the stock nut slot of any fretted instrument. Zero Glide provides four frets of graduated heights to assure you perfect action at the first fret. This breakthrough system reduces contact between the string and the nut by 93% for greatly increased tuning stability by allowing the string to return to its original pitch following bends or aggressive playing techniques. An added benefit: open-string tone becomes the same as fretted-string tone!

Zero Glide Benefits:

  • 93% less friction
  • Perfect Action at 1st Fret
  • No permanent altering of instrument
  • Minimal wear

Zero Glide Benefits over a Standard Nut

Open String Tone Fret reflects energy, making the open strings more vibrant.
Tuning 93% less surface area. More accurate tuning.
String Bend/Whammy Bar Reduces string binding and "returns to zero" after every tug of the whammy bar or bend
Durability Minimal wear. Needs less maintenance.
Installation Sanding block and razor blade. (Slotted model)

Perfect Action from the start!

Utilizing the "zero-fret" concept, the Zero Glide nut allows for perfect action starting at fret zero. This allows for a perfect action from the top to bottom of your instrument.

I am a beginner to mandolin, but I have played ukulele for a bit over a year. I got an inexpensive mandolin for Christmas, and have been learning about set-up since then. I found out about these while I was researching mandolins with zero frets.Installing it took me about 45 minutes, some sandpaper and some files, I cut the fret with a Dremel. You have to sand it on 4 sides to make it fit. As long as you continually check it, you should be fine. It comes with 4 frets of different heights. I just put the lowest one in and tuned everything up to check for buzzing. There was no buzzing. Then I cut and filed the fret to fit. It says you need to glue it in place, but the string tension seems to be holding it in place just fine.Intonation on fret 1 is now perfect according to a digital tuner. Up to fret 7 intonation is improved. Past fret 7 intonation is about how it was, possibly slightly better.Action height is optimal now. String spacing is even and height is even as well.Overall - inexpensive way to make a cheaper mandolin play like a really good one. 10/10. Great product.
