Muirhead-Wallace 311 tenor trombone straight mute

The 311 tenor trombone straight mute plays with accurate intonation and exceptional response across the entire register.

Muirhead-Wallace mutes are handmade in Scotland.

Straight mutes are by far the most widely used mutes for brass. They are cone-shaped with three narrow corks to hold them in the bell. Sound emerges from the gaps between the corks. Straight mutes generally reduce low frequencies and accentuate high, giving a more nasal, reedy sound. Aluminium straight mutes have a brighter sound than those made of softer materials like plastic, fibre or wood.
