Graph Tech Black TUSQ XL Slotted Fender-Style Guitar Nut (PT-5000-00)

The Graph Tech PT-5000-00 is a pre-slotted replacement nut for Fender-style electric guitars such as Stratocasters and Telecasters, and fits both flat-bottom and curved-bottom slots. It is made from Black TUSQ XL, a man-made material impregnated with PTFE so it is permanently self-lubricating and reduces string binding for improved tuning stability. The pre-cut slots allow a quick install. Graph Tech states the material adds harmonic content and sustain compared with standard plastic nuts.
