A MONDO™ drumhead is defined by its construction style. These heads feature a straight-wall ACOUSTICON™ construction. Mondo heads are stronger, more durable and available in varying degrees of thickness from lightweight (resembling goat skin) to heavy (resembling mule or cowhide). Unlike animal skin, these heads are resilient to variations in weather and climate, making them easy to tune and play in any condition.Type 2 heads come in either NUSKYN™ or FIBERSKYN® 3 for different instruments. Both heads are tunable and come with a high collar, utilizing a straight-wall ACOUSTICON™ construction with a ½" support rim around the outside bottom for mounting with a tension ring (traditional flesh hoop). FIBERSKYN® 3 Type 2 heads fit Klong Yaws, Key-Tuned Djembes, Ashikos,; MONDO snare drum, Tunable Tubanos, Standing Ngoma, and Key-Tuned Djun-Djun.Please allow 6-8 weeks for delivery.
