One other thing to understand is the H9 is an algorithm based unit and using the right algorithm within an FX type is key. Not all algorithms are created equal yet have the same control parameters. This is the nature of the this type of technology. It gives loads of high quality FX at a reasonable price, but might not have the deep dive capability some may want. Other than having a dozen of individual FX and maybe analog this is a great setup. I bet checking out some of @apalazzolo presets will help get a grip on things.
