Some questions for you Helix guys... how much of the unit do you feel like you're actually using? how necessary is the expression pedal? is the looper like what you'd find on the M9? how bad are the current reverbs? how good are the current delays and fuzzes? how necessary are the scribble strips? how seamless are the transitions from amp to amp? can you split a signal with cabinet modeling to Output 1 and a signal without cabinet modeling to Output 2 to feed a power amp and guitar speaker as an on-stage monitor?
