Mine is yellowed/vintagey-looking, but I don't recall it ever being "bright white" even when new.
I also think the NS SFs are nice basses. Pretty hard to beat them at their price point, especially used ones in VG-excellent condition.
I find the narrow neck with it's lack of "taper-to-wider" in the upper registers (e.g.: a-la Fender) and resulting narrow string spacing to be fast, comfortable and easy to play.
Die-hard P-Bass guys may not share that opinion.
