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 (For Taylor Guitars).
Also available in Black Delrin.
Works as described but installation was a pain. I have a warmoth tele neck that I installed it to. I had to cut back the nut slot a little to fit the new bone nut and fret in place. I thought it would just drop in.. I wasn't anticipating that but my skills didn't let me down. I filed the nut and fret down on both sides a little, added some super glue and now it works great. i have a bigsby so tunning is a breeze now!
I bought the mandolin version and fitted it to my Gibson. There's a lot of extra material to remove, but the result was great. Easier tuning (the old nut had tight slots for the A strings), better intonation. Later I used one of the extra frets in the package to fix a tenor guitar. For that, I simply filed the necessary ledges in the existing nut and widened the string slots. It would be nice if Stew-Mac would also sell the offset tang frets separately, for retrofitting to an existing nut.
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 installed this on an old Alvarez acoustic that used to belong to my Dad. The strings had started to buzz badly and the bridge height was maxed out so I knew it must be the nut. Took about an hour to cut down the new nut and shape with the Drexel tool; sided/polished the frets and installed glide nut with the tallest feet wire. Worked like a charm and no more buzzing. Even lowed the bridge down to a reasonable height as well. Great product and easy to install.
The Zero Glide performs like the manufacturer claims it will. It took less than one hour to complete the installation and have the guitar playing. The nut I removed was cheap plastic and the thin wires had cut down into the nut to the point that there was severe fret buzz on the open strings. The Zero Glide cured that and has all of the strings at the same level. I used a disc sander to shape the nut to length and height in a few minutes. About five more minutes and the nut was polished. The installation looks good. I suggest a person view the manufacturer's installation video before doing the installation.
