ToneRidge2 Attack's 2-ply 7 mil construction paired our unique split-level design built right into the outer portion of the head to give it great durability and disburses some of the high frequencies. Dark, punchy, and controlled make this head popular with the heavy hitters in Rock, Metal, Soul, Pop, Gospel, and Country genres. The Tone Ridge 2 series is made with Attack's popular Dynaflex film and our Duracoat coating.
