Trombone Mouthpiece ruff lek series

  • The characteristic of ruff lek, a bird with decorative wings around the neck, is reproduced in a curved shape, pursuing functions, effects, and beauty.


    The position of the lower part of the cup is determined to enhance the rich bass, cohesiveness, and directivity of the sound.


    The gentle shape from the rim top to the inside and the edgy inner diameter provide both controllability and a clear attack. In addition, the wide rim that is flat to the outside enhances durability.


    Champagne gold can be selected in addition to normal silver and gold plating.


    Champagne gold is a gold-plated mixture of a small amount of nickel, which has a beautiful shine like champagne and has a clearer outline of sound than gold-plated.


    By using forging (creating a shape by driving heated metal into a mold), the density of the metal is increased compared to ordinary brass materials, the sound core is produced, and the effect of acoustic processing is also improved.


    Sound processing is MOMO's original processing that improves the spread of sound and bass while maintaining the density of forging.



    Silver plating 35,000 yen

    Inner gold 47,000 yen

    Gold plated 50,000 yen
