Hello, friend!
I can suggest you to install Helix native and try it. During 15 days off trial you surely will figure out sonic possibilities of Helix platform.
Helix may sound harsh in headphones, like any other modeler, that doesn't set right. It can sound naturally warm and, as I believe, can satisfy most guitar players, who spend some time learning to use this piece of gear.
Main advice: don't judge Helix by it's preinstalled presets.
