You really want to scroll through many if not all of the presets and really learn how to use the H9 before trying to recreate classic sounds. Remember, the H9 is not an all in one processor as it only runs one algo at a time. You can get a lot of mileage out of it and there are sounds to it that are unique, but you cant run a chorus/delay/reverb/fuzz at once.
There aren’t any quick and easy shortcuts to this. There is great audio bending power in the box, you just have to put the learning into it.
