Resurrecting this one. I just got a helix LT and 5150 iconic stack. I contacted evh to try and figure out if their switching schematic is short-to-sleeve or not but the guy I talked to had to dig into it and said he’d get back to me. Haven’t heard anything yet. being that the iconic has no midi on board, how screwed am I for switching channels on the amp using the helix? Can something like a disaster area midi/trs box fix this for me or am I totally SOL for switching channels with my helix with this head?
