Product Description

Zero Glide animated installation

No Modifications Needed!

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.
