One of the most adjustable bridges on the market, Full Contact Hardware's Babicz 4-string Bass Bridge is a wonder of modern technology, and sounds fantastic. A direct replacement upgrade for Fender Precision or Jazz style bass bridges. Installs in minutes and offers a "saddle housing lock" feature for added saddle stability. Excellent condition, but no owners manual or mounting screws - you don't want the mounting screws anyway, they were junk. $80 + actual shipping.
