ESM Mouthpiece MCK1 Black Acrylic


Specifically designed for the US market, the MCK1 is ESM's most popular Soprano clarinet mouthpiece. With its small tip opening of 1.03mm and its 18.0mm facing, it is comfortable for most - from ambitious students looking to upgrade to professionals who prefer a harder reed.

The black acrylic material produces the darkest and most German sound of ESM's materials. This is the way to go if you are looking to warm up your sound.

The optional metal ring brightens the sound slightly and makes a more immediate connection with the instrument and is a great option for players who are looking for something between the black acrylic without ring and Heaven mouthpieces.
