TUSQ XL offers vintage looks and permanent lubrication.
The TUSQ XL Jumbo Gibson Slotted Nut (PQL-6010-00) is a replacement nut for Gibson guitars.
Finally, the breakthrough you've been waiting for. Now you can have it all - the great tone of TUSQ, classic good looks AND permanent lubrication. If you love the look of a vintage white nut, but you keep going out of tune when you bend strings or use your tremolo, then TUSQ XL is just what you need.
TUSQ XL is designed to boost guitar tone and performance. This precision engineered nut is made with a specially formulated material which 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 Teflon to improve the tuning performance of the guitar.
If you have an acoustic or vintage guitar, you owe it to yourself to hear the difference a TUSQ replacement nut, saddle and bridge pins make. Compared to standard materials such as bone, Micarta or Corian, you'll hear more harmonics with every note you play when you use TUSQ on your guitar.
TUSQ is a proprietary material that is precision engineered under high pressure and heat. It is specifically formulated to deliver the right frequencies with the optimum transfer rate to the top of your guitar every time. Because of the way TUSQ is made, it is a consistent material that is rich in tone and harmonic content.
TUSQ guitar parts have quickly become an important tone performance tool for some of the world's most renowned guitar manufacturers, luthiers and playing professionals. TUSQ nuts and saddles have rich tone and sustain, without the inconsistency found in ivory, bone and other natural materials. Bone and ivory have hard and soft spots (grain) throughout each piece, hampering consistent transfer of vibrations to the guitar top.
The TUSQ replacement guitar nut is designed to transfer the right frequencies more efficiently from the string to the guitar body. Acoustic guitars come alive. Electric guitars will get a brighter sound and increased harmonic content. are designed to transfer the right frequencies more efficiently from the string to the guitar body.
