I’m late to the reply party on this one. I actually thought this one was closer than the recto one. My guesses: A - Kemper, B - Helix, C - AxeFx, D - Amp. I wasn’t really feeling B and C. A & D both sounded good and also sounded closest to me, so that why I assumed they were the Kemper and amp. Honestly, I was going back and forth between which I thought was which. At first I though A was the amp; however, A sounded a little too polished in the lows, so that’s why I ultimately assumed D was the amp. As for my favorite, I actually preferred A. What’s funny is like most, I assumed the Helix was B because it was my least favorite haha. Cool shootout again.
