I have the B3n and the GT-1B. I'm gonna try using both of them to cover pretty much everything I might need. The lack of expression pedal on the Zoom and the need for an external control pedal on the Boss are a major PITA.

I really could care less about adding foot switches or pedals except for the real estate they take up. With today's technology we should have a compact pedal that does it all. A B5n for bass would cover most anything but.....
