What basses tone can be defined as smooth? I don't just mean no treble, but the treble pressence doesn't sound clicky. Its basically like when you slide you don't hear the frets, but its not a fretted bass. CAn anyone think of a bass that fits this? I'm thinking a passive bass with the tone knob rolled off. however, they tend to loosed definition from note to note with the tone rolled off. I'm just trying to describe a buttery tone, and i can't find the bass that produces it. What do you think?
