The Ebony Pinstripe heads are made with two Mylar plies (10 mm & 5 mm) 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 warm resonance. Ebony Pinstripe’s quick decay makes them ideal heads for the “fat” sounds of Rock and R&B and for those who want more low-end sounds with moderate attack and response characteristics.
