Usually when I do a setup, I'm initially guided by my eyes. I try to do a "first approximation" based on a nice consistent distance between the strings and the board. If the board is curved, I try to follow the contour of the board. Basses vary according to the preferred setup, for instance some basses like the strings to be more or less flat, even if the board is curved. Those are "small differences" IMO. But every once in a while, I run into a bass where the setup is just BIZARRE. Like, the saddle height is all over the place when you're trying to dial in a consistent sound in terms of the string balance and the amount of string noise you're hearing on each string. What's the strangest setup you've ever done, and what about it is unusual?
