There's an action setting that I've gotten used to, it's "medium low" to where the sound'll be pretty clean as you're playing quietly, then get nice and raunchy when you start digging in. Most of my basses are adjusted that way. Let's say I wanted to spec this out for a luthier. I could take measurements with a caliper or some other device, and write the spec to say, "the B string shall have exactly 0.9 mm height off the fingerboard at the nut, and 1.4 mm at the 24th fret", something like that. The question is, would that be "enough" for a luthier to set up the bass the way I like it? The context of the question is, we've been discussing bridges and the idea that with some of them, there's a tradeoff between precision and ease of use. So depending on the bridge I'm using (and maybe the nut), someone could set up a bass to my specs and it still wouldn't be right ('cause the saddles are skewed, or the string isn't sitting quite right in the nut, or whatever). I'd really like to provide a luthier with something resembling a "quantitative" spec for the action I want, the hope being that they can build the bass with this action in mind, and when it comes to setting it up, optimize it so it sounds best at this setting. Is that a pipe dream, or does it make sense to take this approach?
