- Industry First! Equipped with a Silencer Capsule System — 1 Mute, 3 Functions! Switch between 3 types of silencer capsules(Silencer, Blowing, Capsule)— to practice comfortably with adjustable sound and playing feel tailored to your environment.
- Silencer Capsule – A capsule designed for high noise reduction, making it as quiet as a normal conversation. Although it creates some resistance when playing, the noise reduction is so effective that even practicing in the next room will be hardly noticeable. Great for nighttime or apartment use.
- Blowing Capsule – A capsule designed to minimize resistance when playing. Although the noise reduction is moderate, it provides a natural blowing feel close to playing without a mute, making it ideal for daytime practice without worrying about disturbing neighbors.
- Tone Capsule – A capsule filled with sponge to minimize changes in tone quality across all registers. It also offers moderate resistance, making it easier to play in the lower register.
- Lightweight & High Strength! Achieves both lightness and high strength with a special structure only possible with a 3D printer.
- Compact size fits inside most bells, making it easy and convenient to carry. [Note] May not fit depending on bell shape or case design.
