Thank you for viewing. This is a one-owner item purchased new about two years ago. It is in beautiful condition with no scratches or stains. All functions have been tested and confirmed to be working. There are no issues with the faders, encoders, or keyboard touch. It has 88 keys but operates on bus power only. The keyboard touch is light and smooth, making it easy to play and giving the impression of faster finger movement. A sustain pedal is not originally included, so you will need to purchase one separately. Thank you.
