I've been playing an electric bass for nearly 2 years. I gig with a four piece band called Hoss. We play classic rock and blues. My technical ability is adequate for the task but I have a long way to go. I had a recent idea that with the right electronics I could do something interesting with my voice while playing the bass. I can sing in the bass range but I'd like some help figuring how to do what I could best describe as supplemental bass sounds or vocal fills through an additional piece of equipment. It might sound like a deep-voiced Bobby McFerrin meets the effects pedal. Any ideas on how to accomplish this or even whether it might add to a rhythm section? Thank you.
