Possible mass change by the mounting number of weight. You can have the best tuning that fits your feeling. In addition, "STB-MSX", recombination into the option of carbon weight "STB-CM", is also the standard weight and hybrid mounting can, you will be further expand the width of the tuning

The donut, set by the top disk of STB-MSX / STB-HWX downward. By EP adapter part of φ38.1 it is fitted into the hole in the donut, and function as EP stabilizer. EP adapter part has a subtle taper toward the top surface, follow also the variation in the donut of the pore size. Just to fit in all of the donut. The donut-other than the record (EP · SP · etc ...) board, and set the top disk of STB-MSX / STB-HWX upward.
