The new YHR-671D features a variety of exciting design changes for the advancing student or professional horn player while retaining Yamaha value, quality, and consistency. Through the Yamaha design philosophy of vertical integration, this professional model offers many of the same high end updates and innovations as the new Custom YHR-871D. The new YHR-671D incorporates modern features into a traditional horn design. A thicker rim wire and a gold-brass leadpipe combine to create a beautiful rich tone and consistent airflow that will provide greater sound character and encourage the best performance in any player. Nickel-plated brass rotary valve caps help sustain durability in this professional model and provide the time-tested quality Yamaha is known for.
