The box is Gotoh, and the contents are Charvel. I think the quality is quite high because I heard that Gotoh makes the Charvel tuners. I like the cute Gotoh logo. I think it's probably not sold separately, so you'd have to buy a Charvel, which costs about 160,000 yen, to get it. I took these out when I converted a Charvel I used to own to a locking type, but I'm not using them, so I'm selling them. - Brand: Charvel - Color: Silver - Type: Guitar Tuners - Quantity: Set of 6 Thank you for looking.
