Purchased new around the beginning of 2024. It's an inch-based tremolo, not metric. I've previously installed it on a Jazzmaster I owned. The three screws on the faceplate are positioned so they sit between the strings, preventing the strings from touching the screw heads when a Buzz Stop bar is installed. Furthermore, the arm is a pop-in tremolo arm like the Mastery tremolo, which clicks into place. The tremolo hinge has been improved, allowing for deeper arming and expanding the vibrato range. I've kept it in storage since removing it from the guitar it was installed on. As a bonus, I'll include a genuine Fender black arm cap. I bought it for this tremolo but didn't really use it... This tremolo costs around 29,800 yen when new. How about it for those who were interested but couldn't afford it due to the high price? Please refrain from price negotiations. #jazzmaster #jaguar #ジャズマスター #ジャガー
