This is a brand new 200 cm  in length, 2-prong power cable that is used on most classic Roland and Korg Synths. If your Korg or Roland Synth has a rectangular jack hole with 2 pins this cord will probably be the one you need!  The rectangular plug is approximately 7/16" (1cm) by 3/4" (2cm) with the holes space approximately 3/8" (1cm) apart.
