"This Korg RK-100 Is 30 Years Old And Has Been Used ALOT In Small Clubs From Florida To NY, But Is In NICE Shape Considering. I Have Included Several Pics And If You Look, There Is A Small Crack That Has Started In The Upper Body, But It Works Great Regardless Of The Cosmetic Wear. It Operates On One 9 Volt Battery And The Battery Cover Is Missing As I Got Tired Of Unscrewing It To Replace The 9V Every Few Days. It Will Also Run On A 9V Adapter To Save On The Cost Of Batteries." eBay Link

"Works great with power cord (not included but available at any electronics store for around $15). Also works on batteries but sometimes needs battery adjustment if they aren't set in just right (a new battery pack would be suggested, available on ebay for under $20). All of the controls are in good shape and work as they should. There are a few scratches on the front and many (beltbuckle) scratches on the back. Has 2 solid strap holders. MIDI In Jack. On/Off button." eBay Link
Works fine and no issues!
The only noticeable imperfection would be near the top of the neck on the back it has a less than 1cm indentation that is barely noticeable.
Also the back of the instrument is also near flawless with no gouges, visible scratches or dents/bashes of any kind.
Instrument comes with 4ft long great looking hard case with blue velvet inside that fits keytar, cords and strap perfectly. Case has slight wear but is in otherwise great condition.
Comes with 2 straps - black and YELLOW." eBay Link
