Does using the whammy bar on the Guitar Hero games increase your score?

Contrary to popular belief, it actually does not give you any extra points. Using it on star power notes can help you get a lot of extra SP. Although after playing many of my friends in Pro-Face Off mode in GH2, One person will use the whammy bar and the other one won't. (because the one controller is broken.) and we will both end up with the same score. That's kind of werid!
