Multi-effects unit for bass. Includes the main unit and the included carrying case only. No box, power cable, or manual. Operation has been confirmed using a DC power supply. I believe it's a beautiful item with little signs of use. Please be aware that this is not a new item, so those who are sensitive to such things should take caution. Thank you.
