An Excellent Product!

Apr 30, 2016

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.

Now that I have it setup I love it. The kits should have all available nut wires in it. I had to special order the largest wire for my Martin Dred kit because the included were too small.

This is a great upgrade not just for replacing the nut but adding the zero fret gives some tone clarity on the open strings . Easy install no issues glad I did it .

A Zero Glide should be the ONLY to go on your instrument.

May 3, 2018

I have 3 instruments with a Zero Glide nut that I play regularly on shows and in jam sessions. My Gold Tone OB 150 has one as standard equipment from Gold Tone. Next is my Martin D custom Acoustic and next is my Washburn M3SWK F body mandolin. I did the install on those last 2 instruments. YES, you WILL have to do some fitting. Follow the instructions to the letter on this. YES, you may find it to be a pain but the gain is more than worth it. Once the Zero Glide is installed and once you start playing a few tunes, you will wonder why you have not installed a Zero Glide nut a lot sooner.

No more string binding issues, no more graphite in the slots or any grease either. You don't need that stuff anymore. No need for nut slot files either with a Zero Glide unless you get one un-slotted. You will still have to fit the Zero Glide nut so you can make it a part of your instrument. No getting around that. It is all part of the fun so enjoy the pain and take your time with the fitting. Once that is done, the action at the first fret will be perfect. Your tone will be better. You will get some sustain you haven't had before. The Zero Glide nut should be the ONLY nut to go on your instruments. I like what it does for playability and tone.

Love My Zero-Glide Nut

Sep 27, 2016

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.
