I finally broke down and bought an H9 core so now I run two H9s. While many of the H9 algorithms do combine two effects, so much depth is added by having two H9s so that I can get two effects at once. With that said, a huge downside is that you need to keep track of which combinations you want to have at the same time. I use a midi controller, so for the most part, once I set the right combination, it works fine. But often I change things on the fly for different songs and also loose track of which combinations I have planned out and which are just randomly set. While I do not have and have not tried an Axe, I assume that it would be cool to set and save pre-planned presets. I also wish the H9 had distortion, which the Axe does. Of course, as currently setup with only being able to have one algo at a time, if you ran distortion on the H9 you wouldn't be able to use the cool H9 algos you want. So, with all that said, I too really wish more than one algorithm could be used at one time.
