I know as much about bass electronics as I do about building H-bombs, why my question might seem stupid to those who are familiar with the subject. Is it possible, in a passive bass, to have separate volume AND tone controls for each pickup? Say, in a Jazz bass you'd have 2 volume and 2 tone controls, without any battery-powered EQ involved. If so, wouldn't this be a cool idea? And if it is a cool idea, why am I yet to actually see a bass with that setup?
