These are Grover Keystone button tuners in gold, originally equipped on a Custom Shop Les Paul Custom I purchased two years ago. I had them replaced with locking 502G tuners at a workshop shortly after purchase and have kept them in storage since. I've only handled them during test playing, but being from a Custom Shop product, I believe they are highly reliable. I wiped them down with a cloth before listing them. I am selling them to organize my equipment. All six nuts, washers, and screws are included. I have stored them in a GROVER 502G package, so I will ship them as is. ※These are not 502GK※ ※These are 102GK and are not locking tuners, so please be aware※ GROVER Rotomatic tuners, gold finish, for precise tuning. - Brand: GROVER - Model: 102GK - Color: Gold - Features: Rotomatic #Gibson #ギブソン #CustomShop #カスタムショップ #LesPaul #レスポール #GROVER #グローバー #エレキギター #ペグ Thank you for looking.
