We adopted a size structure based on the proportional relation between diameter and depth, which is “For every 1 inch increase in diameter, increase the depth by 1/2 inch”. As a result, we successfully achieved the classical tone and lingering depth which is fundamentally different from that of existing concert toms. Solving a conventional problem that tonal color and length of sustain differ between toms, this model offers a perfect unity in tone and sustain as a whole set, which gives you a higher level of expressivity. It also has a wide tuning range from high to low register to allow you to produce various types of sound that is required in classical music.

* 6-inch diameter tom is designed with shallow depth with its special use in mind.
