This is a used YAMAHA French horn YHR-664D for sale. It has been serviced and both the rotary valves and slides are in good working order. This is a Kruspe-type full double horn (professional model, yellow brass, lacquer finish) manufactured by YAMAHA from 1986 to 1994. The original retail price at the time of release was approximately 450,000 yen (when new). It is now a discontinued model. It is very similar in construction to the current YHR-668D, and is recommended for those who like instruments with resistance and want to play powerfully. It is also a model characterized by its ease of playing high notes and its rich, full sound. → Regarding the YHR-668D, there is a product description on the YAMAHA website. (https://jp.yamaha.com/products/musical_instruments/winds/frenchhorns/yhr-668/index.html) ※ The Kruspe type refers to the position of the 4th rotary valve on the left thumb side, which, with its complex winding, provides moderate resistance and results in a rich and dense tone. ※ The bell is a detachable bell (removable bell cut) specification, making it easy to store in the case. There are minor scratches, peeling of the surface treatment, and dents due to use, but the movement of the rotary valves and the smoothness of each slide are very smooth, and there are no major deformations that affect the performance. ※ The 4th rotary valve switches between F/B♭, and currently, pressing it results in B♭. If you prefer the reverse, please switch it before use. ※ A mouthpiece is not included. Please prepare one separately, such as by purchasing one yourself. ※ Includes the hard case shown in the photos (color: brown). ※ In the midst of the rapid price increase of new instruments in a short period, this is a very affordable used item. ※ We will consider price negotiations. We are flexible and actively willing to negotiate as we want to sell it quickly. Thank you for looking!
