Thanks so far...
So i will just go with a normal pedal...
Mission seems to have good PR guys, if they sell a pedal as Kemper pedal, which is not really supported
The Mission pedal is at least informally supported by Kemper (I don't know what they needed to do, to be able to advertise a pedal specifically for the KPA) - the Remotes at NAMM had two pedals connected - a Mission Pedal, and a Dunlop DVP.
The Mission pedal works for Wolf, the way he described it. Another user had problems getting it to work - I've not had a chance to try it, so I can't speak from experience.
HEY, MISSION: If you would like independent confirmation that your pedal can be used for Wah/Volume within a single rig, send me a pedal, and I will post a first-had review of it
