High quality Fender replacement Jaguar Jazzmaster six saddle nickel plated and chrome bridge assembly. Features threaded nickel saddles, chrome U channel bridge with two threaded legs with black pointed height adjustable rocker screws. Very similar to the bridge found on American Vintage Series Jaguar and Jazzmaster. Best used as an affordable replacement on import and replica instruments. This is a complete ready to install bridge unit with all springs and screws already installed. Thimbles and saddle height wrench included. I measured 73mm between the two black rocker screws. Portion of thimble that goes into the body is 8.89mm, upper lip that sits on the top of the body 12.04mm, overall height 21.61mm, inside diameter of leg hole is 7.99mm. It's hard to measure the string spacing of a threaded saddle bridge exactly but I got 2.188" or so (55.58mm) E to E.
