So, I'm looking to have a bass with black barrel style knobs, but I really like the way that the Fender Jazz bass has the nice white line indicator. Can I get black barrel knobs that have such a line indicator? And can they come in the different sizes as well, for the volume and tone controls? I could get used to a different control setup, but I don't see why I should have to. I could just put fender style knobs on, but they wouldn't suit the aesthetic as well. I just like the nice white line, and the size difference. Is there anything like that?
