Zemaitis users, I think you'll get a significant change and satisfaction just by switching to this!! This is a scalloped nut (Gibson type). The material is bleached cow bone. String spacing is approximately 7mm. Please check the width and thickness in the photos. For general guitars, you can replace it without major modifications. The HISASHI signature model has a nut width of 42mm, so it's closer to the original specification. When installing it 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 is also made to resemble the original. The first photo is from the official website. Please compare them. The scalloped nut is famous for being installed on the original Zemaitis guitars made by Mr. Zemaitis himself and the GLAY HISASHI signature model. Even if you don't have a signature Zemaitis, you 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 more distinct sound separation! #gibson #fender #PRS #Epiphone #zemaitis #ESP #Gretsch #Rickenbacker #Suhr #tokai #Fernandes #Fujigen #Greco #electricguitar #guitarrepair #guitarparts #guitarcraft #glay #hisashi
