Ebony Mute Uma (Bridge) for Okinawa Sanshin - A * We offer repairs, maintenance, and karakuri (tuning peg) adjustments for sanshin. Please feel free to contact us. This is an ebony mute uma (bridge). Compared to a standard bamboo uma, the volume is reduced by about 40% (approximately). Ideal for nighttime practice when you can't make loud noises! Length is approximately 150mm, width is approximately 6mm. The size varies slightly for each one. Please consider the photos as a reference. Some may have different colors or patterns, but there is no problem with the muting effect. The wider the part of the uma's foot that contacts the body, the quieter the sound. Compared to the mute uma B, which is listed separately, this one is narrower and the sound is louder. * Uma (bridge) only. Sanshin, chigaa (sound box), and teegaa (skin) are not included. ※※※※ ※※※※ ※※※※ ※※※※※ We are listing Okinawa sanshin and related items. Thank you.
