From Loot Ninja:
"If you're serious about getting better on drums for Rock Band, there's some modding that needs to occur with your kit. First and foremost, you need to replace that flimsy pedal that ships with the system. It just doesn't give you the feel and performance you need for the hard and expert levels. The best way to instantly improve your drum play is to pick up The Destroyer Pedal. This thing is utterly amazing. It's a real drum pedal modded to work with Rock Band."
