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.
I recently custom installed a ZerO Glide on my 40 year old 12 string guitar and it really has done the business. There has been a marked improvement in volume and sustain tuning is much smoother and the intonation is spot on.
I bought this for a Washburn Oscar Schmidt OE-40B archtop guitar, on which the nut had broken when putting on new strings. I always wanted to try a zero-fret nut and was pleasantly surprised at how well it works. Perfect string height and tone.
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
Love the zero glide nut! It makes my open strings ring longer and clear like a fretted note making chords that incorporate both sound more even. It took almost no time to install on my stratocAster and I'm going to mod my Tele now too.
