Pearl Protone 13-Inch Vellum

With their own ProTone drumheads, Pearl show that they know that the shell is just part of your sound. ProTone heads are specifically designed to provide great tone and durability, and really are a cut above the usual stock drumheads. This 13-inch PTH-13 head is made of a single ply of clear mylar, and offers great attack and a beautiful, clear tone.
