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 Resonator Guitars & Lap Steels.
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.
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 just put the Zero Glide on my guitar. Very impressed. This is as close to perfect as I can get. I can bend all over the guitar and 95 of the time the notes come back to the original pitch....the few times they don t it s so minimal most people wouldn t notice it....I really believe that it s probably the tuners....they re decent low grade tuners. Nothing special. Amazing considering this is a 300.00 guitar. I checked the space between the 1st fret and the E and B strings fretted at the third fret...distance between 1st fret and bottom of string .....they looked like they were less than a thousandth and the guitar was not buzzing on an open string. The action is very low with extra thin strings on it. This made the guitar play even easier. I had the strings set at about 4 thousandths from the first fret while fretting at the third. This took them lower....especially on the first 5 frets. Good job on this I do wish they would have sent me a smaller fret.
