What is the Difference in TUSQ Materials?

TUSQ

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

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.

    Works great

    I have wanted to upgrade my strat with a Floyd Rose system but not enough to install the locking nut. I put this Un-Lock nut on it with the existing trem and its tuning has improved dramatically.

    Great product for anyone using a floyd rose but hates using a locking nut. Just ad this with locking tuners and you're all set

    These are fantastic

    I haved used these on 3 guitars now. I have been using them on builds with necks I that have a floyd shelf but on a non-locking trem guitar. Super easy install, had to sand a couple a little narrower and one a little off the back to get the action lower, but that is it. Great tuning stability. I am unaware of any other such solution curretly available. Thank you for making these.

    Incredible Nut for Floyd users

    I was skeptical at first due to the neck shape of my Jackson Kelly Jeff Loomis. With some small dabs of CA glue the nut stayed on with a shim under it with 0 issues moving. I bought some new Graph tech locking tuners to replace the stock ones. The tuners are so good!!! The trem is blocked so it will only dive bomb. Overall the stability is incredible with bending strings and playing for long periods of time. I gave this 4 stars due to the 6 and 4th strings binding when dive bombing. Overall I think this is an incredible nut and will work perfect for headstocks with a straight pull or head stocks with less angle compared to the Jacksons. I plan on using this nut for my non-jackson guitars.
