Forget who played what. This issue is down to the bone--what tool works for you, the individual player. My bass has eight knobs and I use them all, because, as 811952 said, those knobs effectively transform the timbre of the instrument, so I only need one.
I went through umpteen-milllion basses before I settled on my Series 2, and it does everything I need it to except dirty, but we have pedals for that.
The key idea is, what allows you to speak what your heart feels that very moment? For most of us here, Alembic allows that (that's why we hang out here), never mind the number of knobs or how much the artistically-designed shapes neck-dive in real-world situations (much respect, Susan!). My cousin the guitar player loves Washburns, because they speak to him, and it's good he found something that did. For me, poring through endless variations of continuously variable Q and relative pickup volumes, plus the chronic over-engineering, allows me to express myself. I know I can get the sound I want, and the instrument won't fail.
I was just playing along with a CD I recorded 10 years ago and damn, do I wish I'd had Little Black&Tan then. My tone was great, but my inflection was lacking.
