Because we're playing contemporary christian music, everything has something ambient added to each performance on the Kemper. All of that "wash" goes out to the phone and to my in-ear mix. On the left side of Garage Band there are these effects. In the Vocal option there are many effects option. Currently Ambient Vocals is selected. This is what is adding that enhanced tone that I'm missing when getting the in-ear mix. Though the guitar has all that "wash" added into the guitar signals, it still sounds flat and dry, and not more three dimensional.

Several people has suggested the same thing, add the ambient tone to the Kemper. As I said it's already there so I need something added Post. I guess I'll just have to request it and see what happens.
