Metal cup mute features sliding cup portion to allow changes in tone color. Slightly brighter sound and somewhat quicker articulation than standard fibre cups. Excellent for orchestral use. Fits small and medium bore tenor trombones with bells up to 8 inches in diameter. Felt-covered stem and neoprene piped on cup for bell protection. Weighs 8.8 ounces (0.25 kg). Made in USA. -cdp
NOTE: Yamaha YSL456 medium bore trombones should use the large cup (item 01795) instead.
