Innovative cup mute for tenor trombone.

Soulo Cup Mute for tenor trombone offers the best of both worlds: an adjustable fiber mute with the classic cup sound. Unlike the old-school cup mutes, which sound amazing but struggle with pitch, Soulo Trombone Cup is perfectly in tune in all registers with no 'squirrely' notes.

Soulo Cup Mute for trombone is considerably lighter (only 6.6 oz.) than other metal or stone-lined adjustable cups, which typically weigh 8 oz. or more. It is perfect for performance and sound recordings, as it will never fall out the bell due to its weight and its unique neoprene composite corks.

This adjustable cup makes for a great straight mute in a pinch when you completely removing the cup part. The adjustable settings allow the trombone player to blend perfectly in a section that contains different brands of cup mutes.

The Soulo Adjustable Cup Mute is endorsed by US and international trombone icons like Tom Bones Malone and many more.
