The Helix is my first modeller and I'm totally overwhelmed about the functions, the sound, the variability. I had used a lot of amps over the years - H|H, Fender, Hiwatt, Marshall, Boogie...and none of them made me really lucky at the end. And don't aks for the money I spent on pedals. ;-) And now the times for tap-dancing on several pedals are over.
I'm certainly grateful to live in this age of digital modelling! :-) And there's still so much to explore!
