The Pinstripe Clear from Remo is special because the Pinstripe ring that sits between the double layer of mylar is wedged. This is of course not for nothing: these drum sheets have an absolute top quality and a great sound. The drumvel consists of two 0.178 milimeter Mylar sheets with the Pinstripe ring in between. The ring muffles high overtones and provides better resonance. The drum sheet has a short sustain with a very warm sound.
