Great product, Makes a lot of difference in sound and play ability. To say nothing of staying in tune. I put one on a Ovation Legend made in 1972. The guitar always sounded good but was a little tough to play. This made a world of difference. It is now amazing. I have a friend who can't keep his hands off of it. He likes it better than his Rainsong.
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.
One for Fender Telecaster, the other for Breedlove acoustic. Both of these guitars are top 10 instruments. The Zero Glide nut improvement came through as described on Youtube demos. So much better string action (lower with out any fret buzz) Clarity in open string tone chords and pulloff plucking, faster tuning to pitch, using electronic tuner, remaining in pitch once strings stretch has settled in. I took my time to install on both guitars about 2 hours for each instrument. Have new custom Guitar that I will 99% sure I will add this improvement to soon. I see this becoming a standard upgrade to many popular manufactures. Lastly the sustain in open chords on all strings cant be described.
Resolves the nut-string height issue with a simple and easy installation. Worked perfect on my Heritage 16.
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
