Yamaha silent Brass System for Trombone

The Silent Brass System consists of the ST9 module and practice mute.

The newly improved ST9 Personal Studio has been reduced in size and weight to approximately 1/4th that of the earlier version. It has tiny amplifier which offers a choice of clean or reverb enhanced sound. It lets you hear your own playing at the volume you are accustomed to while other hear only the practice mute. The Aux-In is a direct line in for playing along with CD's or other recordings.
