Sorry to high jack your thread but I have a beginner question along the same lines. I'm using the Kemper with a Headrush 112 strickly for home use and streaming online. I too get that muffled bass(y) sound coming from the 112. I copied all the settings every suggested here. My questions is...
Where should I have the master volume dial set to on the Kemper? Does it need to be cranked coming out of the Kemper and then the volumes adjusted on the 112 to get close to a true sound from the profiles?
