I'd like to make a suggestion for an H9 feature (hopefully this is the right place for this kind of post!)
I wish there was a global "Boost" parameter in the System menu, that would allow me to add a specified amount of boost, for example from 0-20 dB, that I could then turn on/off in real time by assigning to an Aux switch.
That way, I could eliminate my current boost pedal that I use for some extra solo volume, and it would also allow me to run straight to 2 amps in stereo (since my boost pedal, like most, is mono and sits at the end of the effects chain – right after my H9).
I don't know if this would be technically difficult or even possible, but to me it sounds fairly straight forward and would hopefully be a useful feature to many others as well.
Thanks for a fantastic product!
