The Hipshot A Style Bass Bridge has become one of the most popular high quality bass bridges available today. The bridge is machined from a solid block of brass for superior quality and tone, the saddles are nested into channels to remove any sideways motion and are individually intonatable and height adjustable. The string spacing is 19 mm as standard but each string is adjustable in the saddle to give 1.5 mm (0.06") side to side adjustment for better string, pickup and neck alignment. The Hipshot A Style Bass bridges give you the choice of either top loading the strings through back of the bridge or mounting them through the guitar body for the tone you prefer.
