Based on in-depth acoustic analysis with feedback from Yamaha artists, the Yamaha YCH-6018 and YCH-7018 deliver rich, fundamental tones and luxurious sustain. Designed with both professional orchestras and school band programs in mind, the larger YCH-7018 provides players with long sustain and a wide dynamic range — giving percussionists the power to stand out in large ensembles, while the YCH-6018 has a lower playing position by 10 centimeters.
