Rubber plunger mute designed for trumpet and cornet. It features a flexible rubber construction that resists drying and hardening over time. The mute includes a front finger holder for better control during performance. It is part of the Stone Lined series originally developed by Willie Berg in 1935, known for consistent quality and tonal performance.
This model is commonly used to produce expressive “doo-wah” effects and growls, especially in jazz and big band settings.
