This is a synchronized tremolo bridge for a Fender Mexico Stratocaster. The tremolo block height is 43mm, so the back cover may not fit depending on the body thickness. The tremolo arm hole is angled. I didn't know this, but apparently, this is the default for Fender. The saddle hex screws are inch-sized, so regular hex wrenches won't fit. It has various unique features, but I think it's quite good for those who like a classic feel. Other than that, the fixing screws, tremolo springs, and arm are not genuine products, but compatibility was not a problem. There are no noticeable scratches, but there is a history of being installed once. Please understand that this is a used item before purchasing. There are no accessories other than those shown in the pictures. If you have any questions, feel free to comment. Thank you! I do not accept price negotiations.
