☆We are a drum head manufacturer that produces highly uniform drum heads using innovative ideas and computer control.☆ This head was developed for power hitters and is the thickest head released to date, with a 10mil 2-ply + 3mil patch (attached to the back) for a total of 23mil. It features a thick, powerful attack and a dry sound with short sustain, and is highly durable and responds well to even the most delicate ghost notes. The LEVEL360 specification ensures a perfect fit the moment you place the head on the shell, allowing you to quickly find your desired tuning. <LEVEL 360> The new structure allows the head to fit snugly against the bearing edge of the drum shell without stress, by finishing the entire 360-degree circumference of the head horizontally and making the corners more vertical, thereby widening the internal diameter. This is a proprietary EVANS technology that makes tuning easier, expands the high and low frequency range, and provides tone stability and improved sound quality. Thickness: 10mil+10mil+3mil patch Finish: Coated with Patch size: 14 inches
