I own both of those pedals and think the TC Electronics stuff is great. However, with the new Kemper reverbs I'm surprised that you're running outboard reverb and delay. I haven't done any A/B testing between them, though. Is there a big difference in tone quality?
To be honest with you, there is not much that the TC pedals do that the Kemper doesn't. In fact the Kemper does ducking and that the TC pedals need to use a tone print slot to be able to do. I still have those two pedals left over from when I had my Archon. I have been thinking of trading them for an over drive or something but not sure what to get. Have also thought of selling them off and possibly a couple of other things to get an MT15 amp again.
