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.

Would be nice to get a 41mm width to replace the Floyd Rose R2 lock nut with the correct string spacing.
A little bit of sanding and it worked well regardless.

Fit and string spacing was good. Height needed a slight adjustment but was to be expected. It sands down very smooth and easy. Having this nut is a tone advantage as well over the metal locking system. Get yourself a set of locking tuners and good to go.

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
