I love pedals, even though the KPA kind of renders most of them kind of obsolete. I've been using "Till's Recto Clean 2" profile (all effects locked to off) for playing with pedals, and it works pretty well. Bright yet neutral. Good for checking out various effects - delay, modulation, reverb, etc., as well as distortion in to a clean amp.
Some of the high gain profiles take a Tube Screamer pedal really well, sending it in to mayhem - in a good way. An analog TS pedal can be a creamy, smooth thing...
Anybody else have a favorite profile for checking out pedals?
