20B has a multi-layered felt structure similar to the 24B, however it is heavier and has a larger core in order to provide the necessary volume and sound one needs in the romantic repertoire like Strauss or Tchaikovsky. The felt is layered in a way that above a mezzo-forte dynamic the mallets produces great articulation but a beautiful, full and warm sound.

“Heavy Roller”: Especially useful for low notes like one would encounter in Bruckner Symphonies, this perfectly balanced mallet produces the biggest and fullest sound a player would ever need in an orchestra.
