The most popular style orchestra mute, or, as commonly known, "conductor pacifier" for the bass. Snaps around the strings below the bridge, so it stays handy even when not in use for its legendary bass-muting powers. Durable black rubber lasts for decades of making your bass slightly quieter, and setting conductors' minds at ease that the whole section is so visibly muted during those Con Sordino passages. Other notable attributes: they bounce, and they make good non-destructive projectiles for getting another's attention during rehearsal. This career-boost for a mere $6.99! At this price, you can get enough for your whole section.
