Good stuff

May 15, 2017

I m impressed with this. Easy to install. I m not a luthiar but I have refretted a few guitars and made some nuts and saddles. This is a pretty incredible system. I was going to cut a new nut for an acoustic guitar I just bought. I tested it and it was not sliding perfectly through the nut even though there was no ping while tuning. The way I test a nut is to strike a note then smack the string between the nut and the machine heads. behind the nut I put a tuner on the head stock so I can watch the note go up and come back. It simulates a good bend and you can watch the quality of the nut you have on the guitar. Most guitars will stick at about 6 to 10 cents above the tuned note unless you have a really well cut nut. At least the wound strings will....steel strings will usually drop back to the tuned note if the nut is decent . The nut I had on this guitar was pretty good....no pings while tuning yet it would still catch occasionally which effected tuning.

Single best upgrade I ve ever done

Jan 11, 2025
Replaced a stock plastic nut on my Squier Jaguar short scale bass with a zero glide today. Hand down the best upgrade I ve done to that or any instrument since I ve started playing. Action is now perfect intonation is spot on tuning is even better/easier as there is less friction to deal with. My initial reasoning for this upgrade was to minimize any nut work needed when changing string gauges now I just have to set intonation and tuning and it s good to go I didn t expect the immense open string clarity change nor did I expect that this bass could get any more sustain out of it but I stand corrected I ll be upgrading every bass and guitar I own to a zero glide now If you re on the fence just go for it - you won t be disappointed

glue it

Jun 23, 2017

I've used this for over a month and I'm more happy now than when I first installed it. The intonation on my acoustic is better than it ever was...you can fine tune the saddle almost dead on for intonation. One suggestion.....be sure to glue in the zero fret with a few drops of glue once you get the guitar right. I was working on my guitar on and off for a month and didn't glue in the zero fret. I was taking the strings on and off. Every time you reinstall the zero fret it will be in a slightly different place. String against fret will cause a slightly different indentation in the zero fret. You want the string to stay in the same spot on the zero fret.

Zero Glide is an amazing product.

Oct 16, 2017

I bought a Gold Tone OB 150 Masterclone banjo that is equipped with a Zero Glide nut. This nut is amazing. YES it will help with tone. No more string binding with Zero Glide. Ever notice on a new instrument how when you are tuning up and on occasion you hear a sound like a string is catching in the slot You will not have that issue with Zero Glide. Once you actually play an instrument with a Zero Glide nut you will notice some differences. You may want to outfit all of your stringed instruments to Zero Glide. No need for slot files to set the action at the nut side of the neck. No more smoothing out string slots with high dollar files that snap really easy. No more using graphite or grease on the nut. Zero Glide takes care of that. Might be the first healthy choice for a nut for your instrument. Get one and install it. You will love it.
