This is another style for futozao shamisen. Rather than the solo-centric tsugaru style, the Gidayu style was developed to be played along with plays. This style uses a bachi with 7mm thick tips. For reference, the tips of bachi for tsugaru shamisen are between 1~2mm, so 7mm is seriously thick stuff. The koma is around 19mm tall. The extreme sizes/thicknesses of the accessories lend to the unique tone of gidayu shamisen.
