Trumpet Case, with Practice Room Feature - dark green
Designed by Sao Paulo Symphony Orchestra principal trumpeter Gilberto Siqueira and built by Marcus Bonna, the GS Studio case doubles as a portable practice room. Unlike a practice mute, even the very best of which impede air flow and change the playing characteritics of the horn, the GS case acts instead as a muffler. Stick your bell into the case, start playing and the sound level is dramatically reduced with zero affect on your chops, airflow or any other playing aspect. Check out the vide below for a live demonstration (the audio is in Portugese, but there are English subtitles).
