I heard that the only problem is the fact that you can’t use the solo fret buttons at the base of the GH guitar, for obvious reasons. Can anyone confirm this? Much appreciated.

Yes you can because I tried it before. Actually, the GH2 controller can be used on any Guitar Hero Game and that RB is compatible with almost any guitar, mic and drums.
