Not compatable with RB/RB2?

[Kerane]

Is this not compatible with Rockband 1 or 2?

I think that you can play Rockband 1 & 2 (I don't have these games myself). But you need to configure you're control plugin properly. If you have LilyPad then tick guitar under pad options (pad 1).
Hope it works for you!

I mean like, the disk itself wont work.
