I think effects use is hard. I don't mean stomping on an effect before a solo like a dash of salt and pepper, but rather musically integrating one or many effects for dramatic effect like a complex sauce. Perhaps working the expression pedal with precision to shape every note precisely. Clicking on one pedal for thee notes for maximum effect then clicking it off. Who are the bass players who are virtuosic in their use of effects and what are their best recorded performances?
