The Horn Guys - Humes & Berg Stonelined 171 Small Cup Mute for Bass Trombone
Order your custom Marcus Bonna case through February for delivery in May. The (delayed) chaos tariffs don't include brass instruments or non-USA-made items, yay!
Similar to the tenor trombone cup mute, but bigger, CAN FIT large tenors like Bach 42, and small bell bass trombones like Conn 70H-73H. Needs thicker corks for modern bass trombones. Fits the 9" Conn 88HK bell. 242g
