A closer look, however, reveals significant improvements under the hood that put this bridge in a class of its own. Hipshot worked hard to ensure that the KickAss™ possesses the soul of the beloved original without being a knockoff. Adjustable string spacing from a narrow .687" (17.5mm) to a wide .800" (20mm) and anywhere in between thanks to fully adjustable pre-notched brass inserts. Features recessed string ball holes for a sleeker, sexier look. Made in Korea.
