Chrome top-loaded bass bridge assembly for Mexico Standard series basses manufactured from 1991-present; also retrofits on most basses with vintage-style five-screw bridge mount design. Looks almost identical to the '70s style Fender Bass bridge except that these have allen head saddle height adjustment screws instead of slotted head screws. Four single-groove "barrel" saddles. Each bridge saddle is height adjustable with two allen head screws and length adjustable for intonation with a single phillips head screw. The bridge plate measures approx. 3.125"X1.75", mounting centers of the string holes on the back lip of the bridge are approx. .75" apart. Mounting screws and wrench included.
