Jazzmaster and Jaguar six saddle bridge assembly, threaded saddles*, U channel bridge with two threaded legs, nickel plated. As found on American Vintage Series Jazzmaster and Jaguar, also fits older guitars. It's hard to measure the string spacing of a threaded saddle bridge exactly but I got 2.188" or so. This is a complete ready to install bridge unit with all springs and screws already installed. Thimbles included. Fender does not include a bridge cover with this bridge. Brand New. Genuine Fender 0054460049. UPC 885978929030.
*The bridge was originally designed for a '60s vintage guitar with 7.25" fingerboard radius. The bridge itself does not have a fixed radius because the individual bridge saddles are height adjustable. With the appropriate 7.25" and 9.5" precision radius guages I was able to easily adjust the saddles to both measurements. The bottom line? This bridge will work fine with necks with a fingerboard radius in the range from 7.25" to 9.5". Additional measurements? I measured 2.866" (72.80mm) post center to center. It should be noted that ALL of the 'generic' (some are actually sold to Fender for import models...) and USA Pro bridges we sell have almost identical post spacing. Body thimbles for this bridge require a bore hole slightly less than .354". Photo may not reflect current Fender packaging.
