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

Best for Electric Guitars and BASS.

    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!

    Makes a great guitar even greater!

    You guy have some serious alchemical mojo going on with this product.

    Getting it to Vietnam was painless and went extremely smooth.

    Thank you.

    I will be putting an order in for 4 more and some saddles soon enough.

    QUALITY!

    Excellent quality as usual, perfectly spaced. What truly sells me on buying direct is that the specs for each product are so clearly defined.

    PRS Piezo 2 Nut Replacement

    I recently installed the Model 6643-00 Nut Slotted L42.95mm Tusq Nut on my PRS Piezo 2 guitar.

    Even when winding on a new set of strings, starting from the E 6th and up, my ears instantly picked up on a new-found overall resonance on the guitar due to the new nut installation. I highly recommend Graph Tech products, they are always of the highest quality. I now have Tusq Nuts on 4 of my guitars, the next to receive one of these nuts will be my Epiphone ES 339. Thanks Guys!

    Prs replacement graphtech nut.

    I have graphtech nuts on my guitars, they give a great tone. Minimal effort to install. The best upgrade to start with to improve the tuning stability and tone.

    I also have the Ratio tuners which are also a great upgrade.

    Thank you,

    Clay Morrison
