This is a set of Kluson-style tuning machines manufactured in the Fender USA line. As shown in the third image, the position is fixed with pins instead of screws, so when using it on guitars other than Fender USA/MEX, you will need to drill holes in the guitar body. Please refer to the following for detailed specifications: https://jp.fender.com/products/classicgear-tuning-machine-set *This is a replacement part for Fender USA/Mexico Stratocasters/Telecasters, but please note that it cannot be used on the American Vintage series. *Returns and refunds due to the buyer's circumstances after shipping (e.g., not reading the description carefully, no longer needed) are not possible. Please understand. *Due to the nature of the product, some modification or adjustment to your guitar may be required.
