I purchased this item from an auction site about two years ago, but I haven't used it much and have been storing it at home. I have confirmed that it powers on. Before listing, I connected it to LIVE and checked the operation of the main buttons. As of now, I haven't found any particular problems, but I haven't comprehensively tested all the buttons and functions. Please consider this when making your decision. Also, there was stickiness (hydrolysis) due to aging from the time of purchase, but I have cleaned it with ethanol. (The cleaned item is shown in the photos from the second image onwards, following the first photo. The area around the Ableton logo is also clean.) Currently, there is no stickiness, and the plastic surface is exposed. Please check the condition in the photos. During the pre-listing inspection, I noticed a chip on the bottom right corner. This item comes from a non-smoking environment. There are no smokers in my family, and I do not have any pets. The item includes the main unit only. *USB cable is not included. Please purchase only if you understand that this is a used item. If you have any concerns, please ask questions. If you would like to negotiate the price, please feel free to comment. Thank you very much.
