You can use any guitar. There are several new features of the game supported by the "World Tour guitar" which is packaged with certain bundles of the game.
The World Tour guitar:
For details on the World Tour guitar and general gameplay issues concerning the guitar, please go here.
Drums
You can use any drum set. If you use the Rock Band drum set, the highway will only have four lanes with the orange pad being mapped to either green or blue depending on what makes more sense for the song (this occurs with any Rock Band set, regardless of any cymbals add-on. It looks like RB cymbals will be supported and allow five lanes with an upcoming patch.).
The World Tour drum set:
Drum set with a MIDI input. For details on the World Tour drum set and general gameplay issues concerning the drums, please go here.
Vocals
You can use any USB mic.
The World Tour mic:
