Vandoren BD5 Bass Clarinet Mouthpiece - Model: BD5 - Type: Bass Clarinet Mouthpiece Used for about a month. Since I used a mouthpiece patch, there are some patch marks and scratches on the surface, like those from a ligature. There are no scratches on the underside, which affects the tone. Like the BD series, it is characterized by its ease of articulation and clear, round tone. I am selling it because I have fewer opportunities to play the bass clarinet.
