Was wondering... Is there a book out there that teaches bass (theory and technique) by using covers?
I took lessons for over 4 years mostly to developed proper technique. Now, I just practice covers and get better by learning new songs and practicing my ever-changing set list. Perhaps my growth as a bass player isn't going to jump by leaps and bounds, but I'm always where I need to be in order to gig, and that's what is important to me. I think your idea is very practical.
