No, you have to use all five pads on GHWT for Wii. GHWT is not compatible with Rock Band drums on the Wii. However, Rock Band 2 for Wii is indeed compatible with the Wii Guitar Hero drums so if you are willing to shell out the money for it, you can play Rock Band 2 for the four-pad experience.
yes
only for rock band 2 and any rock band games after that.
a guitar, microphone, and drums
No it will not.
no because wii is compatible with no other console than GC
Yes.
No, it does not have the right connections.
Yes the game comes with the drums, guitar, microphone and the actual game.
Yes. And it also works vice versa.
you can use the rock band 2 wii drums in guitar hero 5 ive tried it for wii and you need proof heres Hungry Like The Wolf (Guitar Hero 5 Wii Expert drumlook that up on youtube and you got some proof.
If you just need to fix up the drum pad sensitivity, the pads snap off and on easily. (Disclaimer: I have Rock Band 1 drums for the Wii, so I'm not responsible if this isn't true for RB2 drums too) If you want to take it apart for another reason, just snap off the drum pads and unscrew all the screws.
