.....in several years. I learned how to play by ear and by tab. In later years it has been YouTube. I can play ODell or Leon Wilkinson lines, but I have no idea how they create them. Good walking bassists mystify me. I have dibble dabbled over the years, but never worked on it. I have bought books and paid for subscriptions galore. Most I never complete because I am always learning covers or the field is so vast I don’t know what to focus on. I have also never stuck with a teacher. Yes I can play, but the goal? Build killer bass lines on the fly. That’s what I told him. I need someone to guide me in what to focus on. More will be revealed!
