What is the Difference in TUSQ Materials?


TUSQ nuts have a rich tone without the inconsistency found in ivory, bone, and other natural materials. Bone and ivory have hard and soft spots (grain) throughout each piece, hampering the consistent transfer of vibrations to the guitar top. TUSQ nuts are designed to transfer the right frequencies more efficiently from the string to the guitar body.

Best for Acoustic Guitars.


TUSQ XL and Black TUSQ XL nuts are designed to boost guitar tone and performance. These precision-engineered nuts are made with a specially formulated material that couples the strings' vibrations to the neck and brings out the hidden harmonics and richness in every note. It is based on the highly resonant TUSQ man-made ivory but is permanently lubricated to improve the tuning performance of the guitar.

Best for Electric Guitars and BASS.

    Perfect Fit for EC-256

    The cheap EC-256 is - when lucky one the wood part - a great modding base. The 6642 fits out of the box and is most propably the best replacement for the original (2022 model).

    There's talk about the 6143 being the perfect fit, which is plain wrong.

    This one fits, as seen in the picture. The replacement is easy even for a complete beginner as you can see. I did a gentle amount of sanding (400) to smoothen up the bottom though.

    If you like a Graphtech nut once, you can expect the same level of satisfaction both in terms of product and service, every single time.

    It's Great!

    Real buttery slots for those thick gauge strings. Love the way that my D just slips right in there all nice n' cozy like. This is the best nut I've ever experienced and trust me when I say that I've had more than my fair share!

    Much better tuning stability

    Upgraded a cheap nut on a Harley Benton LTD EC-1000 copy and it fit perfectly, as well as works great to provide much better tuning stability.
