The B3N looks like a good (actually, better than good) place to start; 3 footpedals that can be assigned to any custom effect you like (3 overdrives for example), and if memory serves, then they can be scrolled to the side, to use the pedals for two more effects (chorus, octaver, or any combination thereof) - they can all be switched on individually too, or save patches for each song, and name them whatever you need to.
