Best Brass e-Brass III for Trombone (mute)

An evolving mute design for over 15 years.

Besides perfect pitch and less back pressure in all registers, e-Brass achieves a very natural air flow like an open instrument. These leading features were created by carrying out a through investigation of the ideal acoustical design of something we call the total "Instrument", comprising a horn, a mouthpiece, and finally the mute.
This original design approach allows the e-Brass' to be a part of the instrument and also allows for the instrument to resonate naturally while competing practice/silent mutes just kill the sound. Further, as the instrument is still resonating with the mute, the headphones allow the listener a more pure sound without any unnecessary electronic controls.
