Man, those Hipshot bridges can be awfully idiosyncrattic. They can be a real pain to get locked in (from a setup standpoint), probably because they're so precise. A minuscule turn in either direction will make the string sound completely different. But boy, once they're locked in, what a great sound! These F basses are the cat's meow. Mine has a thin spalt top and cherry burst finish, and it finally sounds like an F bass is supposed to. Took me six months to get here, and now it feels like I've finally arrived. Just wanted to share the joy!
