Independent shopping perspective
The Korena take
The Black TUSQ XL PT-6143-00 is a 43 mm guitar nut made from a specially formulated, TUSQ-based manmade-ivory material. Its PTFE impregnation is intended to improve tuning performance, while the material is engineered to transfer string vibration to the neck and bring out added harmonic content and richness. It is a focused replacement part: check its E-to-E spacing and overall dimensions against the nut you are replacing before committing to the installation.
