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.
The Zero Glide performs like the manufacturer claims it will. It took less than one hour to complete the installation and have the guitar playing. The nut I removed was cheap plastic and the thin wires had cut down into the nut to the point that there was severe fret buzz on the open strings. The Zero Glide cured that and has all of the strings at the same level. I used a disc sander to shape the nut to length and height in a few minutes. About five more minutes and the nut was polished. The installation looks good. I suggest a person view the manufacturer's installation video before doing the installation.
This was my first attempt at installing a zero glide. It only took me about an hour to complete the install and I am very pleased with the tone of my open back banjo with the new zero glide nut!
I installed this on an old Alvarez acoustic that used to belong to my Dad. The strings had started to buzz badly and the bridge height was maxed out so I knew it must be the nut. Took about an hour to cut down the new nut and shape with the Drexel tool; sided/polished the frets and installed glide nut with the tallest feet wire. Worked like a charm and no more buzzing. Even lowed the bridge down to a reasonable height as well. Great product and easy to install.
