Old Atelier Momo (currently Brass Lab Momo) French horn mouthpiece 32D Silver plated Inner diameter: 17.5mm Throat: 4.3mm Deep V-cup Alexander shank Atelier Momo's characteristic deep tone. Due to the deep cup and large capacity, the sound may be fuller and slightly darker. In my opinion, it may be recommended for those who prefer a dark tone or like the sound of Vienna. (Of course, it depends on the combination with the instrument and the player's style and natural sound.) The current new price exceeds 30,000 yen, so why not take this opportunity to try it at a slightly lower price?
