ESM Mouthpiece RCR6 Black Acrylic


Designed in collaboration with renowned German music journalist and author Claus Raumberger, the RCR line offers a nice variety for experienced players. The RCR6 is very responsive, with some German sound characteristics. It is versatile and great for all kinds of music. It's tip opening is 1.20mm and the facing is 17.5mm long.

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.
