Graph Tech TUSQ XL Flat-Bottom Slotted Fender-Style Guitar Nut (PQL-5010-00)

The Graph Tech PQL-5010-00 is a pre-slotted replacement nut designed for Fender-style electric guitars that use a flat-bottom nut slot. It is made from self-lubricating TUSQ XL, which is impregnated with PTFE to reduce friction where the strings cross the nut and help the guitar return to pitch. The pre-cut string slots simplify installation. Graph Tech states TUSQ XL brings out additional harmonics and sustain compared with ordinary plastic nuts.
