Voodoo Lab

Would all four of these work together without problem? I know it can intergrate with the M9 but with the Mini Amp Gizmo as well? I already own the M9 and MAG.

Also does order make a difference? Can I run Com>M9>PS>MAG, or does the PS need to come right after the Commander no matter what?

The Pedal Switcher will power the Commander so the Pedal Switcher should be the first device after the Commander, after that it does not matter. The Commander will send Program Change 1-10 on MIDI channel 1. You should make sure that these Program Changes can be used to recall the things you want on both the M9 and Amp Gizmo.
