I just bought my first bass, a Highway One Fender P Bass. I've been playing a fender mexican jazz bass with flatwounds and I like the sound. The kind of bass tones I like are deep soul with low sustain. James Jamerson and Willie Weeks are my favorite. My question is what are my best options as far at strings. I've been interested in the jamerson set at labella, but I read that would put a lot of stress on the bass. I don't want have to put much adjustment on the bass and surely don't want to take it to someone and have then set it up. So how thick of strings can I go and what are good choices?
