No you cannot
You can play Rock band with a guitar hero guitar, but you can't play Guitar Hero with a Rock Band guitar.
Yes. You can play any guitar hero game (including Band Hero) with any guitar (including the Guitar Hero World tour guitar.) As long as the game and the instrument are for the same video game console.
Yes, you can
In Guitar Hero World Tour, you can use the guitar and mic from rock band to play. just not the drumset. But anything before world tour, that would be a no.
Yes
Yes, a Guitar Hero World Tour guitar should be able to work with Green Day Rock Band on any system.
you can with mic and guitar, but not drums
I believe that the rock band guitar could play on guitar hero, but guitar hero's guitar would not play on rock band.
No, guitar hero works with band hero, but guitar hero and band hero do not work with rock band and vice versa
Yes. Even though the instruments have different styles, You can still play Rock Band drums, guitar, bass, and vocals on Guitar Hero. yes but say you got guitar hero and you wanted to play rock band with guitar hero guitars but you need the soft where.
