Looks like a hot rodded '70s style Fender Bass bridge. Machined chrome plated diecast bridge with a massive sustain block on the back end. Strings load only through the back of this block. Each bridge saddle is height adjustable with two allen head screws and length adjustable for intonation with a single phillips head screw. There are two slots milled into the base plate for the allen screws of each saddle to keep 'em from moving around laterally. Bridge mounts to the body with five screws. The bridge plate measures approx. 3.225"X2.231". String spread .857" from slot to slot, approx. 2.310" overall. Saddle height adjustment wrench included and five Genuine Fender mounting screws.
