This little box is filled
This little box is filled to the brim with some great sounds. With the pedal and the battery, this makes a fantastic (and plenty loud) busking amp.
It does require some patience with configuring presets (8 presets is plenty) if you want to use it without the app. The pedal control (Control X) helps as a stomp-box and to switch profiles.
Definitely worth the money, my only gripes are:
1) I would love it if there were more software updates to add new base amps
2) It would be even more awesome if I could add the EQ pedal as a separate stack without losing additional FX.
3) I still find the speakers a bit "boomy" but it's a significant improvement on the Spark 1.
