Clear Pinstripe® heads are made with two 7-mil Mylar® plies, and have quick decay, making them ideal heads for the “fat” sounds of Pop, Rock and R&B and for those who want a low pitched sound with moderate attack and response characteristics. The well-known Clear Pinstripe® heads are made with two 7 mil Mylar® plys with a measured layer of a ring reducing agent applied between them at the outer edge of their trademark stripe to dampen high frequency overtones for warmer resonance.
