Selling due to a DJ equipment replacement. I'm quite meticulous, so I don't see any noticeable scratches or stains, but please check the photos carefully if you are concerned. I don't smoke indoors. I've confirmed operation with CDs and USB, and there are no malfunctioning buttons or knobs. Please understand that this is a used item before purchasing. I will wrap the original box in bubble wrap for shipping. If you purchase by noon on December 21st, I will ship it on December 21st (the earliest shipping date due to pickup arrangements).
