yes it works for all 3
Guitar Hero 2 guitars are the same as the Guitar Hero 1 guitars, so they work with guitar hero 1 and 2. If they are for the same system as Guitar Hero 3, then they will work. But that would only be with the PS2 and Xbox.
Guitar Hero controllers work with all Guitar Hero games, which is great! WOO!
yes
Yes.
YES
IT does for Guitar Hero 3, World Tour and Metallica. Not for Guitar Hero 2
No, for example a Guitar Hero 2 guitar will work for Guitar Hero 3. However for the guitar to work it must be for the same system. A xbox 360 guitar will only work on a 360.
Indeed it does.
Yes. Any of the "Rockband" or "Guitar Hero" guitars will work for "Guitar Hero".
You cant, the guitar for number 2 will work on number 3 but not the other way around. =]
yes all GH controlers work on all games
Yes but It will not work for rock band though
