I sometimes gig just using a Zoom B3 and a powered PA speaker and I notice that maybe this is where, tradition aside, amps are heading. When it comes to bass playing our hands are tied and our feet are free. I don't need dials, I need foot controls for all the variables represented on a bass amp's face. Why not put all the bass amps controls on the ground? There's no need to have them up on top of the speaker. Most monitor and audience sound comes out of powered PA speakers anyway. Maybe we'd need powered speakers specially tuned for bass but it seems far better to put the power in the speaker box not the same unit that has the controls on it. I'm picturing a whole new realm of amp systems, foot pre-amps with controls, and separate powered bass speakers. What do you think?
