ZB-13 Unslotted Replacement Nut for Classical Guitars

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.

I just purchased my 3rd zero glide nut. I have one on my acoustic guitar and this is my second on my 5 string banjo. I've had a couple of custom necks built by different luthiers and in each case I went with the zero glide nut in place of a traditional bone nut. I am a believer in all the technical advantages that the zero glide has to offer. On top of being a great product the family and staff at Gold Tone Banjos are simply amazing folks. I've experienced genuine and personal assistance from everyone that I've been in contact with in the company. This goes all the way from the owner and his wife to their children and techs in the shop. After placing my 3rd order online last night I received a call first thing this morning from Justin wanting to make sure that I understood exactly how the nut slots were cut at the factory on the ZS 8 pre-slotted nuts. Justin made sure that I was 100 satisfied. The new nut was finished this morning and shipped same day. If I could give this review a 10-star review I would. Point being is that this is a top-notch company with great personal and corporate values. I give them and their products the highest review and praise possible. Most definitely recommended.

Pretty easy to install - sand it down to fit - pick the fret that matches the rest of your fretboard - couldn't be easier!

Now that I have it setup I love it. The kits should have all available nut wires in it. I had to special order the largest wire for my Martin Dred kit because the included were too small.
