The HX Stomp is invaluable to me. Even if you don't use it to the max, the compression, eq, amp modeling, IRs, even effects like chorus, delay, and reverb are all great on it. Another thing that I really like is the ability to split your signal when using drives so that you don't lose low end. It took me a little while to figure out how to use it but I learned a lot from buying patches and seeing what they did. David Curran, former bassist for elevation who has played for Lauren Daigle and others is getting ready to release his HX stomp patches which I am looking forward to. I have heard him say that the Cali 76 and Noble are his two desert island pedals, so if you wanted to go bare bones that would be the way to go, but if you are looking to use any kind of effects I would hold onto the stomp.
I can attest to this. When I had my ( very much missed) Noble, I ran direct with it, my Cali 76CB and a Korg Pitchblack... nothing else. It was such an easy setup, and sounded simply amazing!
