I live my helix but, I play a wide variety of different music. I'm used to both my Strymon Timeline and Strymon Bigsky and I also use an Eventide space and an Eventide Timefactor. I've been working hard for about 2 months to get some of the verb and delay sounds on the helix that I need without much luck. The Helix has beautiful verbs and delays but they are somewhat utilitarian for me. I finally decided to get a tiny board and bring both Strymon pedals with me. I kinda hate it because I fly a lot, but I really like both of these FXs to be more versatile than what the Helix can deliver. If there was anything that I could improve on the Helix these 2 fxs would be modernized. They're really not up to date. I also use a Fractal Axe FX and it's far more advanced in these 2 areas. It takes me forever to program, but its verbs and delays are better.
You'll never get strymon sound or versatility on the Helix.
I hope this helps.
