Firstly I have no sponsorship with Graphtech. I wish i did, but I don't. This post is about telling people how amazing I think Graphtech nuts are. On every single guitar and bass I own, I have installed a graphtech nut (black TUSQ) because the tone is perfect, and the tuning stability is second to none! I have even left my bass for a week and its still in tune without any changes! I recommend these to everyone on TB who wants to modify their bass to make it the best they can. Just remember to get the clearance above the 1st fret right (capo on third fret) and measure. I have had to shim every nut so far in order to get the correct height, which robs the tone, but it still plays great, so nevermind.
