## Description

graphtech black tusq nut 6 string electric 43 x 6

Review: Easy Fit and a Noticeable Improvement in Sound - Really happy with this. Fit was spot on for my guitar and it was straightforward to install with minimal effort. Once fitted, the difference was immediately noticeable. Tuning feels more stable and overall tone sounds clearer and more consistent, especially when using the trem or doing bends. Build quality feels solid and it does exactly what it’s meant to do without any fuss. Simple upgrade, easy to fit, and genuinely improves how the guitar feels and sounds. If you’re looking for a quick, effective upgrade that actually makes a difference, this is well worth it.
Review: Not for PRS - The nut is brilliant. Improved tuning stability is noticeable, and tone and sustain is also improved. However these are too short for a PRS, there is a slight gap at the edge and can be felt when running your finger over it. Also the E to e spacing is too short. I have now ordered a Gibson nut, quoted as slightly longer and with the correct string spacing.

### ⭐⭐⭐⭐⭐ One of the best, for about a tenner
*by T***M on 12 November 2025*

I got this for a PRS Custom 24. It fits perfectly, is solid, and a huge upgrade for your guitar for almost no money. It's also fairly easy to install, not that that is specific to this nut, but it's a 20 minute job that's easy to do.
