Yamaha S90 XS 88-Key Balanced Hammer Action Synthesizer – Excellent / Mint Condition (V1.06 OS)

Hello!

I am listing my Yamaha S90XS 88-Key Balanced Weighted Hammer Action Synthesizer, purchased brand new in 2012 from Guitar Center.

This keyboard is in excellent condition and functions 100% perfectly. It has remained strictly in my home studio as a practice keyboard and has never been gigged or taken on the road. I have taken exceptional care of it over the years—cleaning it regularly and keeping it under a dust cover whenever it was not in use.

Condition Details:

• Cosmetics: Super clean overall, with only a small cosmetic speck on the upper left panel (please see close-up photos).
• Functionality: 100% fully operational. All keys, buttons, sliders, outputs, and the screen work smoothly.
• Firmware: Updated to the latest official Version 1.06 OS to ensure it is bug-free and fully up to date.

What’s Included:

• Yamaha S90XS Synthesizer
• Original Power Cord
• Original Owner’s Manual
• Original Software CD (Note: Original factory shipping box is not included)

This keyboard has been fantastic to me with a lot of great memories, but I find myself with less time to play these days. I hope it goes to a home where it will be well-cared for and put to good use!

If you have any questions or would like additional photos/videos, please feel free to reach out.

Thank you!
