Who the M400 Trumpet Mute Bag is For
The Protec M400 Trumpet Mute Bag is a dedicated carry solution for trumpet players who need secure, organized transport for mutes and small accessories. It is designed for students, working musicians, and professionals who want a compact way to keep common items in one place, including a tuner, metronome, mouthpiece pouch, valve oil, slide grease, and pencils.
What distinguishes the M400 is its protection and organization: a generously padded body, a soft non-abrasive nylex lining, and an adjustable padded divider that lets you customize the interior layout for your specific mute setup. The weather-resistant exterior, strong custom zippers, and case-attachable backside clip make it practical for daily rehearsals, pits, and travel.
