Multifunction Mute Extra
This version of the Multifunction Mute is designed specifically for the Inderbinen Extra trumpet and its enormous near six-inch bell! As far as I know, this is the only mute on the market designed for this instrument. Available in threaded or magnetic versions.
Includes the mute, four cork sizes, cork storage tray, and spare cork pads.
