ZS-20 Slotted Replacement Nut for 12-string Guitars

Zero Glide Query

Jun 23, 2025

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.

It Really Works!

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.

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 nutted

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.
