The actual game of Guitar Hero is fantastic but this iteration on the Wii is fundamentally broken. audio for a music based game is in mono sound only. I do not have an advance audio setup or an audiophile as some reviews might suggest are the real problem. But if you are like me and planned to play the game in two player mode. Then forget it. As stero is need to determin your played notes. The sound signal for missed notes are misinterpeted and is sent to both players wiimotes. just avoid the wii version untill is it fixed.
