Product Overview
The Graph Tech TUSQ M644 is a replacement nut for Martin-style acoustic guitars and other guitars that need an angled nut; it has an angled bottom.
TUSQ is Graph Tech's man-made ivory. Bone and ivory have hard and soft spots in the grain that hamper the even transfer of vibration to the guitar; TUSQ is consistent from piece to piece, so the right frequencies pass more efficiently from the string to the body. Graph Tech made TUSQ for high-end acoustic guitars and says it gives up to 200 percent more harmonic content and richness than bone.
Choosing the right nut: match it by length, then thickness, then string spacing (center of the low E slot to center of the high E slot). A little longer or thicker than your old nut is fine, as Graph Tech leaves a little extra so it can be sanded to a flush, snug fit.
