This was the label stuck on the rear cavity cover of my Omen 7 & 8. It means that my Schecters were equipped with Graphtech's Black Tusq nuts at the factory.
Is this a case of stamping superiority on one's product? 'Superiority' here is subjective but whatever's the case, I am happy to know that Schecter made a wise inclusion for its guitars. We often overlook the nut's importance when it comes to tuning stability. We often do not make sure it is suitably slotted & lubricated for a reliable performance.
Thumbs up to Schecter for this.
