Anyone tried the Zoom A1 Four Multi Effects Pedal?

It seems like the standard G1 Four version is quite popular, and I recently stumbled on the A1 version designed for acoustic instruments – including harmonica. Nevertheless, most reviews and discussions on the internet still focus on guitar use, although there is a good discussion on YouTube about using it with violins. It comes with several effects and patches built specifically for harmonica use, though. Besides Zoom’s demo, there is one third party video that runs through the various pre-loaded harmonica patches here: [ZOOM A1 FOUR with Harmonica - YouTube]
I’d really be interested in hearing an assessment from harmonica players who are familiar with using various pedals, pre amps and cabinets. (It also includes a green bullet simulator as one of the effects)
