Scalloped nut (Gibson type). The material is unbleached cow bone, oiled since around March. It is oiled again after processing. String spacing is approximately 7mm. Please check the width and thickness in the photos. This is a scalloped nut, famous for being used on original Zemaitis guitars made by Mr. Zemaitis himself, and on GLAY's HISASHI signature model. Even if you don't own a signature Zemaitis, replacing your nut with this one will allow you to get closer to the look and sound of the original. For Les Pauls, SGs, and other Gibson users, this unbleached version will blend in visually, and you should be able to feel the sound separation effect of the scalloping. It can be installed on general Gibson and Zemaitis guitars without major modifications. 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. #gibson #fender #PRS #Epiphone #zemaitis #ESP #Gretsch #Rickenbacker #Suhr #tokai #Fernandes #Fujigen #Greco #electricguitar #guitarrepair #guitarparts #guitarcraft
