The Texture Coated Performance II is a two-ply head manufactured with Aquarian's Vacuum Molded Process which eliminates air bubbles and wrinkles between the two plies. The two, 7 mil plies are sealed only at the edges which tame unwanted overtones and puts the focus on the low frequencies. The PFII is designed for loose tuning to deliver that low, fat, punchy tom-tom sound that were a big part of classic rock'n'roll recordings. The texture coating warms up the tone. The built-in frequency control adds focus and power. The PFII is a great head to use to upgrade the sound of low priced kits.
