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 Guitar.
Also available in Black Delrin.
Pretty easy to install - sand it down to fit - pick the fret that matches the rest of your fretboard - couldn't be easier!
Just got a second one. Used the first on a Tele build. The multiple heights included give plenty of options. Takes some tweaking but so does a standard nut and you don't have to worry about overdoing anything.
This was my first attempt at installing a zero glide. It only took me about an hour to complete the install and I am very pleased with the tone of my open back banjo with the new zero glide nut!
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.
