Vandoren BD4 Bb Clarinet Mouthpiece

Building on the success of the very popular Black Diamond BD5, The Vandoren BD4 Bb Clarinet Mouthpiece is the newest edition to Vandoren’s mouthpiece range. A great flexible mouthpiece, that answers a lot of peoples musical needs. With a completely different internal and external design from any of their other mouthpieces, the BD4 offers a full sound, with rich depth and colour.

Compared to the BD5, the BD4 boasts a very slightly larger tip opening and facing length for increased response and ease of playability whilst retaining the sound qualities that made the BD5 so popular.
