Heh, I thought of a new way to do the best bassist thing. !?! Marcus Miller, my favorite jazz and slap player, especially as his is deeply rooted in blues rock, funk, with a solid rhythmic groove. I was early on impressed with Jack Casady and John Entwistle. Noisy rock bassists With lots of top end growl! More recently I’ve a deeper appreciation for bass heavy bassists. My favorites, Lee Dorman on the In a gadda da vida album. Really great sound with upper bass/lower mid definition. And Stephen Stills on the CSN album. Deep, broad Fender tone. Like Wooden Ships.
