I disagree with this analogy. Or, more accurately, I disagree with the conclusion you draw from it. If the bass is the meat, it's impossible to literally "make a meal" out of just the seasoning (unless you've got an oscillator generator pedal...but even then you're really closer to a synth player than a bass player). And there are plenty of meals that (while, yes, they don't consist solely of seasoning) are DEFINED by their seasoning. Curry for one, most serious BBQers will tell you the secret is in the rub or the sauce.
So go ahead and define your sound by the metal gizmos, the only thing that matters is if it's tasty.
