[Accessories] Spark Amplifier Power Adapter USB Cable Quick Start Guide Please refer to the manufacturer's website for connection methods and other instructions. An unused dedicated carrying bag is included, making it easy to carry around even when you're on the go. I've only connected and played it a few times.
