I have run the Rook Royale as my main overdrive for about the past 2 years. I can do everything with that box that it used to take 3 or 4 pedals to do. It is super cool that you can switch the order of the boost and drive. Plus, if you put the Rook side into the distortion mode you can get a real Marshally kind of sound. But yeah, you can get a TS sound, a transparent overdrive, an EP booster, and a Marshall Brown sound all in one box. It is a winner.
