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 Ukulele.
Also available in Black Delrin.
I have a Yamaha F310 and the nut was cut real high. Looking around on the internet I came across the ZerO Glide and decided to give it a try. It was less expensive that having the nut cut or purchasing the tools to do it. Printed out the sizing chart and found the ZS-5 had the correct spacing. In less than an hour my guitar felt and sounded great. This is one hell of a product and glad I made the purchase.
I bought a Gold Tone OB 150 Masterclone banjo that is equipped with a Zero Glide nut. This nut is amazing. YES it will help with tone. No more string binding with Zero Glide. Ever notice on a new instrument how when you are tuning up and on occasion you hear a sound like a string is catching in the slot You will not have that issue with Zero Glide. Once you actually play an instrument with a Zero Glide nut you will notice some differences. You may want to outfit all of your stringed instruments to Zero Glide. No need for slot files to set the action at the nut side of the neck. No more smoothing out string slots with high dollar files that snap really easy. No more using graphite or grease on the nut. Zero Glide takes care of that. Might be the first healthy choice for a nut for your instrument. Get one and install it. You will love it.
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 this on one guitar i built and promptly bought another for another guitar. Awesome product. Use them!
