I dunno...TH2 doesn't seem to be as responsive as GR5. By that I mean, the knobs don't do much.
I turn a knob and nothing much happens...I get much better sounds out of GR5.
So for now I'm sticking with GR5 as my goto.
Maybe It's because I'm new to it, and haven't used it much, but I couldn't get a usable sound out of it. I'll play around with it some more, maybe I'll find something I like.
