Used it live as a simple whammy replacer. It's small, requires only a fraction of power that whammy draws - very convenient. You can get even more if you figure out the toneprint editor.
The inconvenient part is that the editor doesn't have any tooltips/hints on how to use it; the "help" section in editor sends you to an "under construction" page. The software IS powerful, but very not user friendly. There are some videos on internet from users(!) on how to create some toneprints. Would be great if the manufacturer did that job, not the users, and more thoroughly. Also you can't share created custom toneprints, which would save time.
The pedal is rather good for the price.
