Coated Pinstripe's quick decay makes them ideal heads for the "fat" sounds of Pop, Rock and R&B and for those who want a low pitched sound with warm attack and response characteristics. The Coated Pinstripe heads are made with two 7 mil 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.
