The fan bois will say just buy the helix and the powercab 2-12 and run in stereo but man thats just too expensive for me. I like the powercab 2-12 concept but not the $1400 price.I was waiting for the same thing from Line 6. I can't justify a Helix Floor (on cost and what options I need) but dreamed of a reduced feature set, with Helix modelling quality, in a combo package that sounded like an amp in the room ... for somewhere in the AUD$1,000 - AUD$2000 range ... that didn't weigh more than 20kg.
It's not quite packaged up as a single combo unit, but I realized the other day that HX Stomp + Powercab would give me that. I can see the advantages of having the two separate units, especially if I ever get around to recording, but I would still prefer a single unit that combined those two products ... with a board to stomp on or change snapshots/patches.
