Scalloped nut (Gibson type). Material: unbleached cow bone String spacing: approximately 7mm Please check the width and thickness in the photos. It can be replaced without major modifications on typical Gibson and Zemaitis 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 scalloped nut is famous for being installed on original Zemaitis guitars made by Mr. Zemaitis himself and the HISASHI signature model of GLAY. Even those who do not own a signature Zemaitis can get closer to the look and sound of the original by replacing it with this one. For Les Paul and SG Gibson users, the unbleached one will blend in better visually. You should also be able to feel the separation of the sound. #gibson #fender #PRS #Epiphone #zemaitis #ESP #Gretsch #Rickenbacker #Suhr #tokai #Fernandes #Fujigen #Greco #electricguitar #guitarrepair #guitarparts #guitarcraft
