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.

    Replacement Nut Blank for S. Yairi parlor guitar

    Graphtech's excellent website allowed me to find the nut blank that fit perfectly on my S. Yairi parlor guitar. After cutting the slots on the blank the guitar sounds great.

    Thank you graphtech guitar labs!

    It works.

    Yes, everything you heard is true. The Tusq XL delivers what it promises, and the blank makes it even more accessible. A must have for vibrato equipped guitars.
