Final Price Reduction Yamaha Flugelhorn YFH-631 Low Brass & Minor Custom Used

This is a listing for a used Yamaha Flugelhorn YFH-631, with a low brass finish and custom modifications. The low brass finish is said to make sub-tones and other techniques even easier to achieve. This is likely the model used by Chuck Mangione. As shown in the photos, while it is an older instrument, there are no noticeable dents or major damage (though some repairs may have been made, it's difficult to tell). Due to the low brass finish, the appearance is free of scratches. Please check the photos for details. The third valve slide originally did not have a pitch adjustment trigger, but a well-known individual added an Amado water key and a trigger to make pitch adjustment easier. Additionally, the heavy weight and mouthpiece pipe screws have been customized. It was used actively until recently without any issues. The reason for selling is to purchase a new flugelhorn.
It is easy to play, but please understand that it is an older instrument before bidding. This is a Yamaha brand, superior to cheaper Chinese or Taiwanese made instruments. Thank you.
