Wow, Eric Klein and the Line 6 team have been busy. These units look amazing. As always they have their finger on the pulse of their user community. I look forward to trying one out.
Looks like a meaningful upgrade, for those who need it.
I'm still using the original Helix. Still does most of what I need, with a few outboard pieces. I wonder if 3.8 is the last firmware they will release.
