Scalloped nut (Gibson type). Material: bleached cow bone String spacing: approximately 7mm Please check the width and thickness in the photos. It can be replaced without major modifications on most standard guitars. Note that the HISASHI signature model has a nut width of 42mm, but most other models are 43mm, so this is recommended. When installing on a Zemaitis, the Zemaitis nut is easily removed, so replacing it or returning to the original nut should not be difficult. The shape of the nut was also made to resemble the original. The first photo is quoted from the official website. Please compare. The scalloped nut is famous for being installed on original Zemaitis guitars from when Mr. Zemaitis himself was making them, and on GLAY's HISASHI signature model. Even if you don't have a signature Zemaitis, replacing it with this one will allow you to get closer to the look and sound of the original. Also recommended for Gibson users of Les Pauls, SGs, etc. who want a more distinct sound separation! #gibson #fender #PRS #Epiphone #zemaitis #ESP #Gretsch #Rickenbacker #Suhr #tokai #Fernandes #Fujigen #Greco #electricguitar #guitarrepair #guitarparts #guitarcraft #glay #hisashi
