The size is M. I've only tried it once. About KATO.B.K. Model Seegers The basic model was created by researching and reproducing in detail the felt wrapping and core materials of the timpani mallets owned by Mr. Seegers. The basic concept is "big sound with soft mallets." With various players, such as differences in physique and playing style, we came up with many ideas and created a vast number of prototypes to allow each player to choose the mallet that best suits them. From these, we carefully selected 20 types (3 original + 17 variations) for the lineup. *The names of the variation models are based on the impressions Seegers himself felt during the trial playing, and are not meant to be rigid requirements, but rather a guideline. This timpani mallet with a special head structure has the excellent advantage of allowing the performer to control the clarity, tone, and rhythm of the sound. The idea for this mallet head has a history of about 150 years, and the materials used at the time included wood, sea sponge, wool, and leather. Currently, wood, cork, leather, and cotton (felt) are mainly used. It continues to develop, as if it has been used in performances in Central Europe for 150 years.
