Keiko Ambe Signature Series, with the advice of Mr. Abue, has made a model that allows you to bring out the most of your instruments and players even with songs that require high performance. It has a much more masculine finish than a typical mallet and is an ideal mallet for marine bists that have a technique above the standard. The yarn spool head shape uses a round shape that allows for delicate expressions even with a mass on the head. Also, the shaft is 3cm longer than usual (except MKA/MKAW-02, MKA/MKAW-03), and fully meet the demands of modern music playing.
