Fully functional and in aesthetically great shape. Has the HKA ROM expander installed for an additional 7 banks of samples from other drum machines. I repaired this unit and installed the mod myself. One thing to note is that the crash fader is using a different replacement potentiometer that I had on hand, so the knob for that post is a little loose. Comes with 12V center negative DC supply. You will need to install AA batteries and do a factory reset to save patches!
