Thank you for viewing. This is a BLACK-13, which reproduces the sound of Scott Ian (ANTHRAX / S.O.D) of Digitech. It works fine with an adapter, but when I put batteries in for the first time in about a year for this listing, I found that it no longer works with batteries. It was only used indoors, and the appearance is good for its age. Please feel free to ask any questions. The price includes shipping. The only included item is the main unit as shown in the image. #Anthrax #S.O.D #ScottIan
