There's good and bad.
Good - comes with original korg power supply. DIN sync tested and works. All drum sounds work.
Bad - some of the buttons are very finicky and the LCD screen is on it's way out. Both of these make it very difficult to program. The switch contacts are readily available online, but i'm not sure about a replacement LCD screen. Either way it's beyond my soldering skills.
These go from anywhere between $400-$600 in good condition so i think this is a reasonable compromise due to it's faults and repair work that needs to be done. Sold asis.
Cash is king. No funny stuff. don't waste my time and yours by lowballing, this is cheap.
