Okinawa Sanshin (Okinawan three-stringed instrument) Ebony Mute Bridge (B) This is an ebony mute bridge. Compared to a regular bamboo bridge, the volume is reduced by about 10%. The sound of the sanshin resonates quite a bit, so it's perfect for late-night practice when you can't make loud noises! Compared to (A), which is listed separately, this has a higher muting effect, resulting in a quieter sound. The length is approximately 153mm, and the width is approximately 9mm. The size varies slightly for each one. Shipping is planned via standard mail. ※※※※ ※※※※ ※※※※ ※※※※※ I am listing Okinawa sanshin and related items. Thank you.
