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.
That completely depends. Is the guitar hero 3 controller for the same platform as the guitar hero 2 controller ? (I.e. xbox 360 or ps2)
yes it works for all 3
