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 impregnated with PTFE to improve the tuning performance of the guitar.

Best for Electric Guitars and BASS.

    Great as always. Fits well on Yamaha FG830

    Fitted very well on my Yamaha FG830 and gave me some more string separation.

    Tusq String Nut

    The string spacing did not work for me the way I thought is would. Other that, the sound of the instrument is much better than the Urea, that is installed on Yamaha acoustic guitars.

    Very satisfied!

    As my new Lava ME2´s head nut was little too narrow for my big european bands, l’ ve directly ordered this M169-00 at Graphtech’s.

    It came to France winthin couple of days and perfectly fits my guitar, increasing its comfort and playability, with an excellent sound an sustain.

    So thank you Graphtech and long live Canada!

    From France with love.

    Turns a $350 guitar into a $1k guitar

    I added the Tusq nut and bridge saddle to a new Dean Exotica quilt ash and the tone woke up.

    The highs are brighter and the lows sound cleaner but not necessarily louder.

    I removed all the plastic from contacting the strings and it makes a noticable difference. Highly recommend
