Thank you for the insight. This is a great piece of gear but after researching, it does not appear to provide the functionality of channel switching between three amps at once, but extremely versatile for effects and looping.
I am looking for a way to switch channels simultaneously between 3 - dual rectifiers using the external switching functionality. I am using a Lehle amp switcher (which I use all three amps at once all the time), but im having trouble finding a foot pedal that will allow me to accomplish this...
