Evans EC2S clear tom heads deliver a tight sound with reduced high frequencies and enhanced attack, thanks to the Sound Shaping Technology (SST) rings on the underside. EC2S clear heads are made with two plies of 7mil film which offers consistency and durability for longer playing time. With a defined attack, short sustain, semi-dark tone, and enhanced durability, EC2S tom heads are great for drummers who want a focused, powerful attack with each hit. This drumhead also features Level 360 Technology.
