Out of interest, how do you have it configured? I run in stereo anyway, so had it as the 2 1/4" outs on the Kemper to the Inputs on the Mimiq, and then the two Mimiq outs to two RedSound cabs (via TRS jacks).
Maybe I wasn't clear on that point. Guitar goes into the mimiq, outputs go to Kemper 1 and Kemper 2. Both Kempers use only one output , and both going into my interface panned left - right. Or if I ever go play live again, into two 1x12" Rocktron cabinets.
