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 12 String Guitar (Blank).
Also available in Black Delrin.
An inexperienced guitar tech worked on the nut of my Guild M75 Aristocrat electric and I ended up with a "sitar" sound on my high E string and a dead G string and bad intonation. A friend recommended Zero Glide and that company recommended this particular nut.
Installation was not particularly difficult for a handy guy, but took two hours and involved sanding nearly 1/8 inch off the bottom of the new nut and 1/16th plus off each side while being careful to keep it even. The video on the company website helps. Once fitted correctly you decide how big of a 'zero fret' you want. There are four of different sizes in the package. I tried them all and found that the smaller ones provide very low action at the nut (which is nice), but require a higher action up the neck to clear the first fret where the strings can rattle. I ended up using the largest fret provided as it allowed me low action where I need it. Once you have it figured out you trim the zero fret to length and glue it
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.
I was having a very hard time finding the right nut replacement for my mandolin. Finally found this one at StewMac. Have never used the zero glide before, but this one works great. Had a good deal of sanding to do for a perfect fit, but it works great and sound is super on my mando. Thanks guys!!
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.
