Guitar NUTS

The guitar nut is very influential in determining how playable the instrument is.

Many playability and tuning problems stem from nut issues. 

There are only two points where your strings contact the body of your guitar, the nut and the saddle. This makes the nut crucial in the "Tone Chain" that affects how your guitar sounds. However, there's more to it than that - the action and playability of the guitar is greatly affected by the height of the strings at the nut, and making sure that this is correct is crucial to your guitar's playability. In addition, tuning stability can be affected if the strings bind in the nut slots. Here's how Tone Ninja nuts solve those problems:

Tone Ninja nuts are manufactured using an engineered polymer that has a very high and consistent density that transmits more of the vibration of the strings to the neck of the guitar.

Tone Ninja nuts are precision slotted and are pre-sized for most common instruments.  Because guitars are made out of wood, they can vary slightly, so all Tone Ninja nuts are made slightly oversize so you can adjust to fit on installation. The material used to manufacture Tone Ninja nuts is easy to work for that final adjustment.

All Tone Ninja nuts are made from a material that has a natural lubricity - which means no more lubricating your nuts with graphite, the nut is self-lubricating. Great news if you have a trem, because the nut won't bind. The precision engineered slots mean no more binding when tuning, solving that problem once and for all.

Guitar Nut Material


Tone Ninja guitar nuts are made from an engineering polymer (more about that later) that was specifically chosen to meet the specific characteristics required of an outstanding nut for your guitar - namely high density (to transmit tone), low friction (to avoid sticking and binding), and easy workability (to allow perfect custom fits) while retaining wear resistance (so it doesn't wear out).

Originally, nuts were traditionally made of bone, carved and slotted to suit. The main problem with bone is that it can be hard to work, and can vary in density. Alternatives were various forms of ivory, which are now, of course, ecologically unacceptable.


As technology progressed, various different materials were used, including brass, graphite, low cost plastic (still used on many entry level instruments and even some higher priced guitars), engineered plastics such as micarta, corian and Graph Tech's Tusq material (which is actually an injection molding plastic called polyphenylene sulfide).


When we were selecting a material for Tone Ninja nuts, we wanted to improve on these materials rather than just imitate them, and as a result selected an acetal copolymer with glass fiber reinforcement because of it's high stiffness, low coefficient of friction and excellent dimensional stability.

Tone Ninja USA Made Slotted Nut Flat bottomed Fender, Musicman White TN-NUT-002-W1

This makes the 4th Tone Ninja nut I have installed on a guitar. I used this particular one as a replacement for the nut on a 1982 Ibanez Blazer BL-470 SB. Just like the others I have installed, this one required minimal modification for fitment. The quality of the nut is great - dense, slippery and toneful. No string binding and improved tuning. Call me a fan. Next time I replace a nut I will likely use a Tone Ninja.

Tone Ninja USA Made Slotted Acoustic White TN-NUT-006-W1

Product does as described, it made my old ovation acoustic clear and crisp again. A little fine tuning for fit and it works perfect. I would recommend it to my fellow musicians. Thanks for a great product.

Tone Ninja USA Made Slotted Nut for Gibson Black TN-NUT-004-B1

Replaced the original Corian nut on a 2013 Gibson SG Future Tribute to address tuning issues. Easy installation with minimal sanding/modification. In fact, the nut slots worked just fine without any filing at all. Nut material is naturally slippery and of uniform density as advertised. My tuning issues are now resolved.

Hello, I just wanted to let you know I really like the tone of your guitar nuts. Any chance you will make an aged cream color Gibson type/ spec nut? I have a white one on an Oscar Schmidt Goldtop and I’d love to match the cream binding it has. I used Graphtech until I came across your products. I notice that your Guitar nuts have a rounder or smoother tone that is very close to some bone I have used. The Graphtech Tusq seem to have more aggressive midrange character, but they sound sterile on clean tones. I did a comparison with Tusq and yours and although the tone is brighter with Tusq, your Tone Ninja nuts seem to sound better in the guitars I’ve put them in. Thanks, Aaron
