Refers to the Harmonix/EA developed game Rock Band. Developed in 2007, Rock Band follows a similar formula to Guitar Hero, but however, focuses more on band-play and features different instrument controllers.. The guitar controller for Rock Band has flat frets instead of the dome-like shaped frets on Guitar Hero guitar controllers. Rock Band drumkits usually have no cymbals and 4 pads/toms (Unless they have the Pro Drums Extension, which adds 3 additional cymbals), while Guitar Hero drumkits have 2 cymbals and 3 pads/toms
