Remo Pinstripe Ebony Heads are made with two Mylar plies (one 10-mil, one 5-mil). The space outside of the "pinstripe" is filled with a measured ring-reducing agent to dampen unwanted high frequency overtones. Pinstripe Ebonys have a dark sound and a fat, midrange tone, while the Crimplock edge prevents the head from pulling loose under extreme tension.
