I'm putting a solid black pickguard on my new Sterling tommorow for a custom look. Does anyone know where I can find some knobs like this?..... Description: Chrome knurled knobs just like on the Sterling, but with a solid black round insert on the top. Solid black insert, NOT a swirl or onyx type. I think that would look pretty good with the black pickguard. Is ther anything different about the Sterling knob fit? Or is it pretty generic?
