"

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 have a BC-350 banjo with the zero glide nut. It has been problem-free but I'm curious how this is an improvement over the zero nut found on budget European guitars since practically the beginning of time. I repaired instruments for decades and always regarded the zero fret as a marker of an inferior mass-produced instrument. No criticism of the Gold Tone zero glide is in any way implied here but I am confused."
