One of the key causes of tuning frustration is string binding at the nut. Black Tusq XL alleviates the binding grip of the nut on the string and reducing friction between the nut material and the string. This is accomplished using a nut manufactured from an engineered resonant base material impregnated with Teflon. As strings move across a Black Tusq XL nut, they shear open microscopic “capsules” loaded with millions of “ball bearing” type lubricants. For strings, it’s like a hardwood floor covered in marbles... strings roll back into tune. It’s that simple! Black Tusq XL nuts are factory-installed by many major guitar manufacturers including Carvin, Parker Guitars, Brian Moore Custom Guitars, Steinberger, and the Fender Custom Shop for good reason: TREM-NUT will keep your guitar in tune longer than graphite, bone plastic or synthetic nuts. In addition, Black Tusq XL has crystal clear tone and sustain.
