Please add me to those who would like better OD and Distortion stomps for the Kemper.
The Kemper is a very successful upgrade from my Digitech RP1000, but I do miss how the TS-9, Modified TS-9, and TS-808 effects worked on that unit. I also really liked the Digitech Redline Overdrive. What I liked about those was how they didn't change the core sound (EQ) of the amp model. They were more organic tweaks to the amp model's natural tone. If Digitech can do it, I know that Kemper can do it. 
Please consider replicating TC Electronic's Nova Drive pedal. It's is an outstanding match for clean and crunch amp settings! What I like about the OD section of that pedal is that it has 4 controls (OD, Level, Tone, and Mix). Here's the link http://www.tcelectronic.com/ndr-1-nova-drive/ . In my opinion, both the OD and Distortion stomps of the Nova Drive pedal would be a great additions!
Thanks for asking for our suggestions!
