ZS-7F Slotted Replacement Nut for Guitars (Common on Fender)

This Fixed It

Nov 3, 2023

The G string on my Epiphone Dot was bound up in the nut and always pinging loose when trying to tune it. It would suddenly be sharp then suddenly flat etc. I installed a Zero Glide on her her and problem solved. Not only that but it has also improved tone. Honestly I was just trying to do a quick fix in order to sell her but the new life in her changed my mind.

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

What sorcery is this ?

Jun 3, 2018

Just put one of these on an old beater of a cheap strat-clone kit that I use to experiment with "creative" wiring. Suddenly its in tune up and down the neck and stays that way after using the trem as well. It cost half the price of the kit but it has significantly improved the value of the instrument to me. It required a little sanding of the back of the nut but nothing drastic. I dont have many dedicated luthier tools so the fret wire is not trimmed perfectly (but the look is in keeping with the overall "relic'd" appearance of the guitar). The question now becomes can I get a discount if I order these in bulk?

I nutted

Aug 28, 2022

I bought one for my generic mass produced bass don't get me wrong It's an awesome bass . I recently had It refretted with jumbo gold bell brass frets and It's regular plastic nut started to feel off. I did a little search on web and came upto this products. I combined It with my leftover gold fret wire and boom I Nutted Finally after years of trying to prevent using open strings on my bass I can enjoy that low open string notes sustaining to eternity. 100 recommended and If you ever get a custom made instrument insist on the 0 fret option. You can try different gauge strings without worrying about nut slot shapes and widths.
