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.

    Perfect

    I didn't have to sand or adjust anything after removing the existing locking nut and dropping this in. My Ibanez has a 17"radius Super Wizard neck and this is perfect.

    Best thing to ever happen to a locking nut!!

    I was having dead notes and fair at best tone with my Ibanez J custom. This nut not only got rid of the locking nut it gave me ultimate sustain, excellent tone and got rid of my dead notes on the fretboard. I am very pleased with this nut I would recommend this to everyone that uses Floyd Rose or locking nuts. What a game changer!! Thank you
