I've gotta say, as much as I love my GT-10B, I could definitely see myself switching to a board consisting entirely of MS-60B's.
Someone here mentioned that you can have one pedal run multiple functions; would I be able to have a noise gate permanently activated, with the footswitch turning a tuner/mute on and off? I was tossing up the idea of having one pedal take care of all my "utility" effects, but my compressor needs to be at the beginning of my chain. So, I figure I could have one pedal at the start with the compressor always on, and the switch turning overdrive on/off, then the aforementioned tuner/noisegate combination at the end. I'd fill the space in between with delay, auto-wah, etc.
