This is a KORG KAOSS PAD KP3, equipped with sampling and effects functions. I am selling it to organize my equipment. There is some discoloration of the buttons and scratches on the body due to aging and use, but I have confirmed that the buttons, knobs, and touch panel function without any problems. Addition: There was some crackling in the speakers when turning the volume knob. It disappeared after wiggling it around, but please refrain from purchasing if you are concerned. There is no effect on performance. - Brand: KORG - Functions: Sampling, Effects - Power Supply: AC Adapter Thank you for looking.
