I'm not an owner yet, but I am very interested in the H9 (or H10 😉 )
I would love to see something like a 4 cable method (maybe using the stereo in- and outputs) to be able to place some effects before and behind the preamp.
Moreover 2 FX at the same time would be great. At least to set a reverb and/or delay behind every algorithm would make me buy the stomp box immediately.
An univibe algorythm is highly appreciated as well.
