I have to agree with Guitarfish, that the included UniVibe-like preset that is included with the Harmadillo algorithm is a bit underwelming to say the least. In my opinion, the UniVibe like presets that are available for the Vibrato algorithm (with mix set at 50%) are far more convincing. 

Of course, if anyone has a preset for Harmadillo that will proof me wrong, I invite them to share it with us.
