The PT-M644-00 is a great option to replace or upgrade the nut on your six string acoustic or electric guitar. Developed for Martin style guitars and can be used with other guitars that require similar nut.

It has an angled bottom and is pre-slotted for a quick and simple install.

Black TUSQ XL is designed to boost guitar tone and performance. This precision engineered nut is made with a specially formulated material which couples the strings' vibrations to the neck and brings out the hidden harmonics and richness in every note. It is based on the highly resonant TUSQ man made ivory, but is impregnated with PTFE to improve the tuning performance of the guitar.
