StompBox is a digital effects unit for the iPad.  It comes with a whole slew of effects ranging from delay to pitch shifting.  You’ll also get 7 different types of distortion for creating those extra grimy tones.  The 4 track recorder is ideal for looping backing tracks and you can easily sort through presets using your feet (in the event that your hands aren’t available).

While StomBox is clearly geared toward acoustic and electric guitar, it’s also very effective for bass – delivering clean, bold tones. The user interface is easy on the eyes and responds to touch well.

There have been some instability issues, but we’re confident that 4Pockets (the developer) will iron out those wrinkles.  If you need some quality effects processors, this isn’t a bad way to go.
