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.

Why we call it zero GLIDE

I will append if all doesn't go well. The bone nut is quite weak for use with 12-strings because it often splits between the close pairs. It should be Tusq, Torlon or PEEK.

Installed the unslotted nut so I could set the string spacing a little wider to accommodate my wide fingers, worked very well. I have the zero glides on all my guitars now.

Only reason I ordered this is because the original Zero Glide I ordered (from another vendor) was not the correct string spacing for my guitar. I ordered a blank so it could be cut properly for my exact guitar. As I don't have the specific nut files to slot the blank nut, I sent out my guitar to a reputable shop for cutting the blank and installing the nut. Once the guitar was done, the nut was too low on the high E sting and was buzzing on open notes. My brand new "drop in" nut needed to be shimmed. I had zero buzz issues with the original nut so I'm not impressed after having buzzing issues after having a professional install a "drop in" nut. It's been shimmed and I don't have any problems at this time. It does what it is supposed to do once installed correctly and I do have improved tuning and better open string tone. It is a little misleading when the advertisements pitch it as a "drop in replacement for $30". My now finished and stable guitar upgrade has easily cost me at least 3 times that.
