I've been playing co-op Guitar Hero 3 on my Xbox 360 recently and have noticed something a bit odd.
I have two guitar controllers, the Les Paul that came with Guitar Hero 3 and the Xplorer that came with Guitar Hero 2. The Xplorer always seems to perform worse, no matter who is playing it. A lot of the time, when you to hit a note the flame graphic on the note shows but the "clunk" sound for missing a note plays as well.
I just did an experiment with the two guitars in single player. Same song, same difficulty. With the Les Paul I got 99%, 200+ note streak and only missed three notes. With the Xplorer I got 98%, 9 note max streak and only missed four notes. A lot of notes went clunk, yet the game was clearly registering them as being hit!
How is this possible? What on earth is going on here?
