Got the Helix now 2 weeks and it did not disappoint me. I had the first POD and the Vetta amps in the past but this is so close to the real thing! The amp-types really sound great over my JMI AC30/6 combo (of course with the cabs sim switch off). Built quality is really robust and heavy so road-proof just like my M13 which survived heavy bumps and some beer spills on stage. I still need to test the Helix in live situations and look forward to gig with it soon. I'm curious on the dynamics and the low freq response as the unit is quite high-tone-happy. But with the right EQ this can be overcome I guess. I also ordered the case for it, a must when you go out with the Helix on stage. Overall: very good and really recommend to check it out!
