I got an HX Stomp a few weeks back, mainly because I was impressed at how John Cordy (YouTube guitarist) was utilising it and how it sounded with his presets. I had the full on Helix for a month years back but swapped it for a ‘78 Marshall JMP combo, as I didn’t like it at all. The Stomp represents a matured feature set in the Helix world and is quick, easy and flexible. It sounds good with the right IR and presets, but it’s no Kemper killer.
Incidentally, I just got rid of the Marshall and got a Fractal FM3 today. It’s on another level with regards to the Stomp and sounds, though wouldn’t fit in the pocket of my guitar gig bag.
