ZB-13 Unslotted Replacement Nut for Classical Guitars

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

Great once installed

Works as described but installation was a pain. I have a warmoth tele neck that I installed it to. I had to cut back the nut slot a little to fit the new bone nut and fret in place. I thought it would just drop in.. I wasn't anticipating that but my skills didn't let me down. I filed the nut and fret down on both sides a little, added some super glue and now it works great. i have a bigsby so tunning is a breeze now!

Acoustic Glide Nut

Oct 7, 2016

I installed this on an old Alvarez acoustic that used to belong to my Dad. The strings had started to buzz badly and the bridge height was maxed out so I knew it must be the nut. Took about an hour to cut down the new nut and shape with the Drexel tool; sided/polished the frets and installed glide nut with the tallest feet wire. Worked like a charm and no more buzzing. Even lowed the bridge down to a reasonable height as well. Great product and easy to install.
