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.

    Nut replacement on Gibson G-40

    Had to make the necessary adjustments to make the saddle fit but after a little careful perseverance the guitar is playing great again. Thanks!

    The right nut for Taylor 1 3/4” neck

    I used the nut on my Taylor 814CE. I was guessing as to the model as there seems to be little info with regards to proper nut for this guitar. The 6400-00 fit very easily and was easy to sand to size. I offset my nut by about 1/16” on the big E string side. This makes thumb-over chords cleaner… I don’t have long enough thumbs.

    TUSQ for Taylor 612

    The PQ 6400 was a good choice for my Taylor, took just a little sanding and it was a perfect fit.

    Great upgrade

    I like how the nut is pre slotted for easy install however I always file my nut slots to reach height rather than just sand off the bottom for fit. Since the slots are already slotted, my files just glide thru bringing the height at the first fret easy for me to obtain.

    The tonal difference is worth the work!

    After a little work it fits in snug and is easy to sand to the desired thickness.

    Replaced the original on my Yamaha FG 331 and it worked out quite nicely!

    Awesome tone!
