The Zero Glide Replacement Nut System borrows the "zero fret" concept to reduce string contact in the nut by up to 93%, increasing tuning stability, playability, and open string tone. It only takes a few minutes to install with absolutely no permanent alteration to your instrument. For Fender Style Guitar.
*The ZS-7F is designed to fit either a flat or radiused nut shelf. Leave the middle nub for flat, or sand it down for a radius.
Also available in Black Delrin.
Note: May not fit specific models. Check the sizing guide to be sure.
Wow, what an innovation! This product eliminates the critical process of nut filing completely disappear to be replaced by a zero fret which enhances the sound of your guitar. It is not without some challenges in installation, but once completed your guitar just sounds and plays better.
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.
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.
This is one of those things that you ask yourself why has no one thought of this before, but it likely would have been very difficult to produce on a volume scale without CNC machines.......I put the ZB4 on a Washburn parlor guitar and was amazed at the difference in tone clarity, sustain and definition as well as tuning stability and the lowest possible action.........What more could you ask for for one single mod??.....Zero Glide makes several different sizes etc to fit just about any guitar, so be sure you get the right model for your instrument. The unslotted ZB4 requires slotting, so it does require some skill and proper files. I would recommend letting a tech install if you have no experience or tools. I do predict that some of the major instrument makers will be using this in the near future. Why did'nt I think of this. JB/Texas
