KORG KAOSS PAD QUAD unit only. This is an auction for the unit itself, and a power adapter is not included. Due to long-term storage, there are minor scratches, marks, and discoloration on the buttons. As I didn't have the necessary terminals, I only tested the sound output from the MIC IN and PHONES terminals. The pad is working without any problems, and since a protective film is attached, I don't think there are any direct scratches. I will reiterate that this is an auction for the unit only. Please understand that the adapter is not included and that this is a used item. Please make your purchase with the understanding that it is non-refundable and non-returnable.
