For those of you who use basses with low action, what's your preferred tonewood for the fingerboard? I'm specifically interested in the low B string for the 5-string players. My experience has been that it's typical in most basses for the B to start making some awful strange sounds when it's set real low, and especially when you start digging in or popping it a little hard, but it really depends a lot on the fingerboard. Usually you can find an action setting where the strange overtones aren't so annoying and the grind is "dialed in", so to speak. Generally speaking the ebony fingerboards I've played have been the most precise, but I do love maple for its snappy quality for slapping and tapping. It just seems the maple boards are somehow less precise, they're "squishier" somehow. Plus they're more likely to generate honking sounds on the B when the string is set really low. Has anyone had this experience? What other woods are good to consider for this purpose? Is the general rule for fingerboards "the harder the better", or would you sacrifice some precision for other kinds of playability and responsiveness?
