Its the total build that influences the tone. The quality of each piece including the hardware and pickups. It is no coincidence that a good handmade bass made by a quality builder -percentage wise - is going to sound and play better than a mass produced one.
This is why with Fenders some people have an Ash that sounds incredible and others may have the opposite experience. I also question when people say something sounds identical if they are playing and listening through monitoring headphones or just live through their rigs. Its really the little nuances that matter with a bass when you record a clean tone. It also matters how close you listen and how much you care. If you are a studio guy you will care more and listen closer, and these little things matter more.
