Just picked up a Korg DDM-110 from a friend. The buttons are pretty beat on the inside, either you get nothing or you get multiple hits. It also sounds like there is a grounding problem that will need to be fixed. So it is going on the bench, and we will see if I can get it thumpin’ again. Then we will see what treasures are hidden inside. Stay posted for more on the DDM-110 including inside shots, repair tips, & possibly circuit bending info.
