I actually think L6 has done a great job of updating this unit over time. I bought mine back in February of 2016. right before 1.06 came out.
Since then they have added a ton of amps, effects, and functionality to the Helix as well as introducing HX Effects, Helix Stomp and Helix Native (which I also have in my pro tools setup).
They have also added quite a few high gain amps for those of us who like it nasty. The Cali IV, the 2204 Mod, the Fatality, Archetype, Badonk, Placater, etc. It already came with Quite a few from Soldano to Mesa to Bogner to Engl, 5150, Several original models, etc etc....right out of the gate.. Now they are throwing Revv into the mix?
That doesn't include the massive amount of effects added.
I'm pretty happy so far and I'm very excited to integrate it with my DT-50 head.
