ZS-3 Slotted Replacement Nut for Guitars (Common on Martin)

A Zero Glide should be the ONLY to go on your instrument.

May 3, 2018

I have 3 instruments with a Zero Glide nut that I play regularly on shows and in jam sessions. My Gold Tone OB 150 has one as standard equipment from Gold Tone. Next is my Martin D custom Acoustic and next is my Washburn M3SWK F body mandolin. I did the install on those last 2 instruments. YES, you WILL have to do some fitting. Follow the instructions to the letter on this. YES, you may find it to be a pain but the gain is more than worth it. Once the Zero Glide is installed and once you start playing a few tunes, you will wonder why you have not installed a Zero Glide nut a lot sooner.

No more string binding issues, no more graphite in the slots or any grease either. You don't need that stuff anymore. No need for nut slot files either with a Zero Glide unless you get one un-slotted. You will still have to fit the Zero Glide nut so you can make it a part of your instrument. No getting around that. It is all part of the fun so enjoy the pain and take your time with the fitting. Once that is done, the action at the first fret will be perfect. Your tone will be better. You will get some sustain you haven't had before. The Zero Glide nut should be the ONLY nut to go on your instruments. I like what it does for playability and tone.

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.

Zeros Are Great

My third build and first time I used the zero fret, made filing the nut slots easier. The sound is markedly clearer than the other bone nuts I've used.

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
