Manufacturer’s description:
‘Wooden straight mutes offer a special warm tone color unmatched by other materials, especially in soft dynamics. The birch faced plywood sidewalls and marine ply bases are lined with a vulcanized fiber to provide superior durability and a warm, earthy sound.’
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. Wooden straight mutes have a softer sound than the brighter aluminium mutes.
