Yamaha Grand Series Double Headed Concert Tom 12 x 10 in. Darkwood stain finish

New Size Structure
After exhaustive study to determine the best size for this model specifically designed for concert use, Yamaha 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, Yamaha designers 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, the 9000 Series offers a perfect unity in tone and sustain as a whole set, which gives you a higher level of expressivity. This series also has a wide tuning range from high to low register to allow you to produce various types of sound that is required in orchestral music. The CT-9015 is a 15" double headed concert tom that will tune easily and perform at the highest levels.

YESS III Mounting System
How a tom and a stand are connected is a very important factor to determine the resonance and tonal color of the instrument. As the best mount system for CT-9000 series, Yamaha adopted the YESS II Mount System. This reflects the design concept of the Yamaha ultra-high-end drum set PHX series drum sets.

By putting the tom in a state close to "hanging in the air" as much as possible without holding it, this mount system minimizes the potential loss where the stand absorbs the instrument's vibration and succeeds to bring out tom tom's original fat tone with longer sustain. A shorten time lag between a point of attack and sound generation allows you to concentrate on your play more easily.

Sizes and Systems
Eight traditional sizes of single headed concert toms are offered in three traditional set-ups: CTG-6802 (6", 8", 10", 12" with two stands); CTG-0234 (10", 12", 13", 14", with two stands); CTG-3456 (13", 14", 15", 16", with two stands).

Air-Seal System Shells
The oak shells are produced utilizing the Air-Seal System. This process ensures that shells start round and stay round; an in-round shell tunes clearer and provides a pure fundamental tone.

Oak Shells
Oak shell offers a fat, dense tone and sharp, open resonance. In addition to these characteristics, longer sustain and quick response is provide by YESS III Mounting System, achieving a perfect balance between tone clarity and abundant sustain. Even when playing a high-speed passage or roll, you can deliver the slightest nuance to your audience.
