The 'solo' break is a two guitar harmony part that you could easily dial on the Kemper. The tone is pretty hot(switch to higher gain profile or medium distortion) with a longer delay. The delay is key and helps smooth out the sound and also helps to get the transition of the held notes into feedback. Of course, you also need enough volume and gain to get to the feedback point.
I've got the solo sound pretty good, it's just the clean intro settings but I'm getting closer thanks to all the comments.
