I think ZEMAITIS users will get a significant change and satisfaction just by changing to this!! It's a scalloped nut (Gibson type). The material is unbleached cow bone. The string spacing is approximately 7mm. Please check the width and thickness in the photos. It can be replaced on most general 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 shouldn't 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 them. The scalloped nut is famous for being installed on the original ZEMAITIS made by Mr. ZEMAITIS himself and the GLAY HISASHI signature model. Even those who don't have a signature ZEMAITIS can get closer to the look and sound of the original by replacing it with this. It's also recommended for Gibson users of Les Pauls, SGs, etc., who want a sense of separation in their sound! #gibson #fender #PRS #Epiphone #zemaitis #ESP #Gretsch #Rickenbacker #Suhr #tokai #Fernandes #Fujigen #Greco #electricguitar #guitarrepair #guitarparts #guitarcraft #glay #hisashi
