No, the Helix doesn't sound better than the Kemper, and it's harder to dial in given the head start that the commercial profiles give you. But I can get it to sound equally "real" and great to me, and it packs features that I've been missing in the Kemper for years. So my Kemper is for sale. It's been a great ride, and I may be back if they ever release a floorboard version.
It's cool Ben, that you found your toy of joy Could you reveal what are the features you were missing in Kemper for years?
