This is an original Yamaha S90 from 2003. I've owned it the whole time. The electronics, the audio, and all the buttons/knobs/keys are in mint condition. It plays like a charm. I've used it to gig recently. The case has some minor scratches along the corners, which you can see in the photos. I feel like this keyboard is a tank and will live longer than I do; so I hope someone can give it a good next home!
