I have the H9 configured for stereo operation with two amps. Sometimes, I only turn on amp number one, however. No problem with many presets but with some, of course, part of the effect is missing (was sent to amp number two). I realize I could unplug the output number 2 jack from the H9 but on a pedal board that can sometimes require a can opener and needle nose pliers. Is there a way I am missing via the App to put the H9 in mono mode? If not, perhaps this could be added to a feature request list?
