New ???? Trumcor Trumcor Classical Bass Trombone Cup Mute ????

TrumCor mutes are carefully handcrafted with wood and a specially formulated fiber material. They create a muted tone that is vibrant, warm and responsive. These mutes are durable, and the wide selection of sizes ensures a proper fit and excellent intonation. TrumCor mutes produce a beautiful sound, and at the same time preserve the noble timbre of the trombone in all registers and at all dynamics. This is the same mute as the Classical Cup Tenor, except that it is sized for bass trombone.
