Guitar Hero 3 button mapping? (wii)

[Socaddict]

Tried a quick google and search, and couldn't find it, but how do the buttons map to the controller when you use it instead of a guitar? looking to play a bit with one of my flatmates, and at the moment, I only have the one controller.

cheers.

can you? are there even enough buttons? for the 360 version its listed in the manual, so I'd assume if it were possible it would be in the wii manual.
