Check the listing for details. Korg DD5 dynamic digital drums With manual AC adapter both covers working Clean. Condition: Used. Listed at 165.00 USD. This is a drum machine that I purchased years ago and never really used it much as the learning curve was more than I wanted to invest my time in.I got involved in other projects. It worked fine when I was using it, but I am not sure if there is any internal batteries that may have pooped out, but it does turn on power up and cycle through the options. This is from A Smoke free environment other than my wood stove. Hey , nice piece of digital vintage history , with its unique korg sound. This comes with the original, AC adapter and the actual original owner's manual.
