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

    Works as described. Needed zero side sanding - was a perfect fit width-wise! Just needed some higher sanded off and it’s perfect.

    Love these

    Love these things, I have them on two guitars now, replacing both a Schaller and a Floyd nut. Greatly simplifies guitar maintenance on both, and seems to have fixed some tuning instability on one of them. In my case, the base of the nut had to be sanded a bit to fit my guitars, or else the 1st fret action was too high. The base & route are flat so nothing fancy was involved, and also the two guitars had different nut route depths, so it seems to be a variable thing which you can't have a "one size fits all" height for. Anyway, I highly recommend these.

    Best upgrade ever!

    Floyd Rose is great, if you have a guitar tech.

    I stopped using them for a long time, preferring an LSR Roller nut and locking tuners.

    I bought an EVH Wolfgang a couple of years ago. I found a great price on one, and I loved the way it looked. I've always loved the D-Tuna. This is a great guitar. When I saw the Un-Lock nut, I thought I'd give it a try.

    I'm so happy I did. It's so nice to be able to tune without tools. It's also great to adjust for next movement without tools. Strings changes still require tools, but they're a lot faster than they used to be.

    The guitar still stays in perfect tune, with the added benefit of not having to fine tune once the lock nut is tightened.

    I've installed these on two other guitars since, and I am 100% satisfied with all of them!

    Great product!!

    Works well and arrived quickly

    Got rid of the locking nut on my 1989 BC Rich USA ST3 and installed locking tuners instead. This nut fitted nicely, gave me slightly wider string spacing (which I wanted) and just needed 0.4mm shim. The locking nut never really worked for me with the micro adjusters so I am happy. I was actually very surprised to receive the nut in the UK direct from Canada in only a few days.

    "Stratonez"

    Used the unlock nut on a Vai JEM neck to put on a Strat body. Neck was brought down to 25.5" scale. Works great!
