New, Unused, and Free Shipping * The "sshhmute" is designed by the world-renowned cornet player Trevor Bremner. It's a masterpiece of a "practice mute," not just for silencing. * Made of durable ABS resin. It won't dent or bend if bumped, making it a mute you'll always want to carry. It's also very lightweight (approx. 180g), so there's no burden from the mute's weight even during long practice sessions. * Slightly longer than a typical practice mute (approx. 19.0cm) and with a larger capacity, it offers very little resistance, allowing you to practice in your usual playing style. Its unique design overcomes the challenges of intonation and tone color when using a mute. You can play with accurate intonation in any register. Thank you.
