The Triad Pad is made of .01" clear polycarbonate film which improves drumhead durability from pedal beater impact. The patented design flexes without distorting sound, increasing attack and improving "punch" without muffling. The thinner gauge badge is best suited for medium-duty general play styles using felt, wool, rubber, and plastic beaters. Ideal for studio recording applications. Not recommended for wood beaters and extreme heavy play.
