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 Fit

    Perfect fit without any modifications. Height of the nut was actually perfect. I would like to have had a little more height on the nut to ensure a proper fit, but I lucked out, and this one dropped right in.

    Get ready to wait on mail.

    The product is great, as all of Graphtech products are. But I will never buy direct from them again. I ordered the product, a week later I had to order another one from Sweetwater because mine was bouncing back and forth from Ca. to Wa. Several times. I received the one from Sweetwater 4 days before I received the one direct.

    Installed on a Chibson ES-355

    After purchasing myself a 'Learning-Luthier' guitar, which came with a broken neck (it was a Chinese Gibson ES-355 replica), after glueing the broken neck back place, I didn't like the plastic nut, so I swapped it out for the Tusq, and man, let me tell you -- I'm one happy camper. The one thing I noticed before and after the Tusq install, were the harmonics... the open string harmonics were much louder than prior -- I don't know; maybe it's a placebo, maybe not... who knows? I don't! Either way, I'm glad I went with the Tusq nut (which fit perfectly by the way)... even tho the Tusq is actually the most expensive thing on the guitar -- guitar included!
