Thank you for viewing. This item is a FENDER Standard Strat Big Block Chrome Tremolo Bridge Assembly. Body only, arm not included. As an aftermarket part, it has a rare string spacing of approximately 10.5mm, so it seems to be often used to upgrade Squier, Fender MEX, and other inexpensive guitars like Photogenic. I used it installed on a Squier Super Sonic. Please note that I cannot answer questions about fitting to other guitars. This is a used item, so please refrain from purchasing if you are sensitive to imperfections or are looking for a product equivalent to new.
