I'm planning to pull the ABM piezo bridge that I had put on my Stambaugh (its going in a fretless project bass), and I need to decide what I should get to replace it. I've seen Hipshot and obviously ABM (don't really like the height adjustment on mine -- the screw barely has anywhere to grip when I get the B string where it needs to be). What I need is truly adjustable string spacing and height, and it has to be available in black. Lofty goals, I know.... If you're kind enough to respond, please tell me how the string spacing works (as the pics I've seen don't really help), and how well it worked for you. OH YEAH! I almost forgot -- its a 5 string.
