| What are you hoping to accomplish? Is it a tone issue or an adjustment issue? Hi mass bridges have "a sound" that may or may not benefit your bass, mostly characterized by making the bass brighter with slightly more sustain. That said both Hipshot and Leo Quan make very good bridges as do Schaller and Gotoh. Regardless of which one you choose, be sure to get something with adjustable string spacing so you can make sure the strings line up over the pole pieces of your bridge pickup. |
