I bought an HX Stomp XL recently to have a bass rig and a backup guitar rig, in case anything happens to my FM9. (Since its is so hard to get a Fractal.) I am still learning the HX Stomp ecosystem but the HX Stomp (Helix) is worlds apart from my FM9. It could be that I am just used to the smoothness of FAS, but yeah, not impressed so far. I put an OD pedal in front and a Specular Tempus delay/reverb unit at the end, and still doesn't compete. When I first plugged in, I was WTH. Seems like a toy in comparison. (I do need more time with it.)
The FM9 is twice the price, but everyone says the HX Stomp is the same amps and cabs as the Helix line, so I was expecting more. I am only commenting to say, yes I agree - the Fractal is well worth the wait. For now, I guess my HX Stomp will be my bass rig, but it really can't compete with my FM9.
