I updated, then after reading the notes, I immediately went to the Dr. Z 38. Per the instructions, I was resetting the amp. I flipped over to the Dr Z - 8 so that I could flip back to the 38, and had already set the cab IR to the UR Amp Factory AC Rox Mix. (kind of a random selection to try out - no reason) What I heard was heaven. I never did flip back to the 38, nor have I tried another amp since. My god what a nice tone. Open chords left open to decay are deeply layered with harmonic content. I can't describe it and frankly have not felt a full amp like relation with the Axe-FX II as organic and harmonically rich as the tone that I stumbled upon by accident here. Volume control and overall dynamic response is amazing. I don't have any idea what this epiphany of Cliff was with V15.xx, but it is real. I can feel it, not only hear it.
I like this - a lot.
