I had the JHS @ (replaced it with a JHS Angry Charlie v3 for more EQ options), I have a HALO, and I will eventually try the Super AT Mod... altho I have heard reports that it sounds less-than-stellar at low volumes; that it's really tweaked to push a LOUD, clean amp... which is of course how Andy uses it. I have owned the Keeley BD-2 (Twice), as well as the Waza. I preferred the Keeley to the Waza, but I preferred the Rockett Blue Note to both (which is what I'm still using for that sound).
I'd love to see someone (like Sweetwater did with the Halo) have a limited BLUE edition- I'd buy it in a heartbeat.
