i was never into the plastic controller guitar thing... Go pick up a real one?

Peavey's got a guitar either out now or coming out that is an actual guitar, but it can be used with Rock Band. How it works, I have no clue. lol

I suppose you could always have it like, how the microphone is set up, basically an inbuilt tuner set to the right notes that tells you if you are off. But then you would just put tabs or notation on the screen. And at that point you may as well just grab a guitar and play along to a cd. :s `so yeah...maybe its not that
