Also of note - the app is free and all but one of the pedals on it are now free as well. Great way to learn what sorts of effects (and different kinds of the same effect) you really like. That's how I've used mine, and it's been perfect. I was able to nail the features of different effects I wanted before I bought, so I wasn't buying numerous boutique effects before settling on the one I liked. They're also pretty good effects in their own right.
