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. Deep bass drum tone the Pinstripe way. 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.
