Recently bought the Impact and was immediately useful out of the box. Fairly intuitive and solidly built. The distortion effect and depth really add to an Alternative/Indutrial vibe as well as the "colour" parameter. The decay and pitch pots are solid and possess a smooth sweep. Adjustment of these parameters cannot be held in pattern memory, so it lends itself better to live use. This is not a great limitation, but causes the individual to consider the Impacts place where studio and live use are concerned.
