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 Gibson Guitar Replacement (Drop-In).
Also available in Black Delrin.
Note: May not fit specific models. Check the sizing guide to be sure.
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.
I bought two of these, one Gibson-style and one Fender-style for two of my favorite project guitars, an Epiphone LPX and my Jazz-O-Caster parts guitar. The Gibson was a near drop-in, needing only some trimming and shaping for a perfect fit. The Fender was slightly more challenging, as the neck on the Jazz-O-Caster never saw the inside of any Fender-approved factory! It required a 1/32" shim underneath for a proper fit, and some sanding to make room for the tang. There was a marked increase in the brightness of tone for both instruments, as well as improved intonation. This is MUCH easier than installing a traditional nut, and nearly foolproof IF you follow the instructions. Thanks, Stewart-Macdonald, for stocking such a well-engineered product.
I wrote another review about Zero Glide and my Gold Tone OB 150 banjo. As many already know the Zero Glide Nut is standard equipment on the OB 150 banjo. Gold Tone has this nut on other instruments too. I like this nut system for a lot of reasons. I installed a Zero Glide nut on my Martin D custom and I even installed a Zero Glide on my Washburn M3SWK F body mandolin. Those stock plastic nuts on many of the entry level pro instruments just does not cut it. You are cheating yourself and your audience out of a lot of tone and sweetness that ears should be hearing. The Zero Glide nut does a world of wonders for my instruments. Do yourself a favor and get one on your axe. You may love it. I know I do. I am addicted to Zero Glide.
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.
