ZS-20 Slotted Replacement Nut for 12-string Guitars

Great Idea And Product

Jul 6, 2015

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

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.

My cheap Les Paul-like copy model guitar used to buzz and was effing annoying so I decided to get this on Amazon. And this made the guitar stop buzzing and look very more great Thanks a lot P.S. I think Gold Tone should get their Store on Amazon so that whoever lives outside the US can buy their products easily.

Love My Zero-Glide Nut

Love the zero glide nut! It makes my open strings ring longer and clear like a fretted note making chords that incorporate both sound more even. It took almost no time to install on my stratocAster and I'm going to mod my Tele now too.
