Our Sympatico System Nesting Ashikos come standard with Sympatico System Pretuned Fiber Heads. At much less than half the weight of traditional hand percussion drums. The Sympatico System of tunable and pretuned, interchangeable drums and heads will change how lightweight drums are perceived. By design, lightweight drums must be portable, dura, andll, light, easy to carry and transport. Unfortunateleliminating bulky and heavy tuning mechanisms is the most common way to achieve this desired outcomesms. In their place is a pre-tuned head. It does the job, it is definitely light, an durable, but the sound is what you get. What if you didn't have to choose between tunable but heavy drums and light but un-tunable drums? The Sympatico System solves this issue with its innovative and proprietary internal tuning design. It's significantly lighter than a traditional tuning system and easy to use, and there's no extra bulky, heavy, hardware attached to the side of the drum to get in your way. In fact, it's hidden inside! And the heads are designed to integrate with Toca's existing line of Freestyle II Nesting Drums. The drums are also stackable - making them ideal for storage and travel! Available in Woodstock Purple(WP) and Kente (K) finishes. 10" drum sizes are available individually. 12" drum sizes are available individually or in a set of 3. These drums are perfect for youngsters, classrooms, drum circles, music therapy sessions, and more. Their durable PVC shells are not only lighter in weight than their wood counterparts, but are easier to clean, and project thunderous tones. Each Sympatico Nesting Djun Djun includes a pair of mallets whose shaft matches the color of the drum shell and is supplied with a full carrying harness to enable the user to play while standing or walking. These Sympatico Ashikos come equipped with Pretuned Fiber heads. We believe that these heads will give you the best sound out of the box. These drums are also compatible with the tunable Fiber heads, Pretuned Synthetic Leather heads, and the tunable Synthetic Leather heads.
