Denis Wick SH4 A mouthpiece supervised by Shoichiro Gaito. This mouthpiece is characterized by a deep, rich sound due to the freedom of Denis Wick and the thick rim, which is a particular focus of Mr. Gaito. The cup diameter is 26.0, equivalent to a Bach 4G, offering both resonance and ease of use. It produces a solid sound that won't be overwhelmed even in a wind ensemble accompaniment.
