Pre-slotted graphite guitar nut from Hosco japan.
These nuts are made from 100% graphite, and offer a vast improvement over or many other nut materials
Graphite is self-lubricating and is a perfect solution for players who use a lot of the tremolo in their playing or have a hard time keeping the guitar in tune. The self-lubricating nature of graphite allows the strings to slide over the nut with less friction, thus reducing tuning issues and hang-ups and increasing sustain.
Please note: Nut may require sanding and shaping for a perfect fit and improved action.
