This is a chrome bridge for American Deluxe basses manufactured between 2004 and 2010. It's an innovative and user-friendly bridge that allows for string-through-body, top-loading, and adjustable string spacing. I installed it to top-load an OPB (instead of string-through-body) and to fine-tune the string spacing. It is not compatible with the typical 5-hole Fender bridge. It is compatible with 3-hole bridges. #TelecasterBass #AmericanDeluxe #AmericanDeluxe
