So to me it was indeed mainly the guitar, which is really wonderful! One can play with the super Anschlager's nice easy to use, but does not slide bar that seems a common mistake in the Wii to be guitars, the bar simply reacts though you do nothing and thus proposes that automatically as a bug in the game, but if you under Options the slide bar is disabled in the game everything was great! Oh, and the game is also great, I have a lot of fun with it :)
