The only instrument ive ever played that was pretty much identical sounding bass to bass was the original Steinberger L2, about as identical as any two fiberglass boat hulls coming out of the same mold, which is effectively how they were built. Every wood bass ive ever played, including brand new, seemingly identical mass produced basses, has sounded a little different. I remember when I bought my first bass, a 78' Ric 4001, I dug through a PILE of, easily 7-8 basses, and they all sounded and felt a hair different. That kind thing never happens anymore, most stores only have a couple, or only one, of a particular bass on display, and wont bring more out until that one is sold. In most cases trying multiple basses from the same brand just isnt possible in a GC. I get it, poorly paid employees dont have time to indulge in a lot of tire kickers, but I've never bought a bass unseen/unplayed from someplace like Sweetwater, which just seems like rolling the dice to me.
