The Korena take
The PT-6643-00 is a black TUSQ XL electric-guitar nut for replacement or upgrade work on Ibanez and PRS guitars, plus other guitars that use a similar nut. Its flat base and pre-cut slots simplify the installation process. The listed dimensions and 1.387-inch E-to-E measurement give you the key references for checking the existing nut before committing to the swap.
