Zemaitis users, I think you'll experience a significant change and satisfaction just by switching to this!! It's 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. It can be replaced without major modifications on most standard guitars. Note that while the HISASHI signature model has a nut width of 42mm, 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 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 original Zemaitis guitars from when Zemaitis himself was making them, as well as on GLAY's HISASHI signature model. Even if you don't own 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
