Graph Tech TUSQ XL PQL 6643-00 Guitar Nut

Better tuning and slightly improved sound. Slots are very well made. I'm very happy. (For Aria Pro II PE-800 guitar. Space between slots were a little bit wider than the original)
Little note on the description: I needed to reduce quite some height and I found out that even with sanding paper 120, some effort is still need (you can use finer sanding paper to finish). Also: the dimensions were spot on, no sanding was needed for length and width.

I have a Harley Benton SC-450plus LD and this guitar nut fits this guitar, BUT is slightly low on height. I had to make a stainless steel piece to place
under it, to raise the nut a little higher. This fixed the problem
and its a very well cut guitar nut. Good string spacing and string fit.
A proper guitar nut makes a huge improvement in sound.
to all guitars.
