Hey y'all, I'd like to know if and how the Helix could be set up to A/B to two separate physical external amplifiers. I have a crystal clean Fender Twin I'd like to use for clean sounds, and a higher gain amp for dirty. I know you can use two different amp models in patches, but I'd like to A/B my Fender Twin and my dirty amps by stomping between patches. It seems this should be fairly easy, but I've yet to see anyone do this. I've searched all over the internet about this, and I have not found the solution.
