The well known Clear Pinstripe heads are made with two 7mm Mylar plies 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. They 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. This standard pack includes 12 13 and 16 drumheads.
