Just got a TritonLab Mustang in on Fri and gave it a go yesterday. It's a Jfet distortion and sounds pretty huge! Harry Maes has a great demo of it(he sold me on it). I haven't got to do a lot with it yet but it is sounding very good on a higher gain setting, very full, articulate and BIG. Won't get to play it live for a couple of weeks but it seems like it's a keeper!
