The Remo Powerstroke 77 Colortone 13″ in violet consists of 2 layers of Mylar film with a strength of 7 mil each, which would also clarify the origin of the name. A narrow damping ring of also 7 mil provides a dry response and a shortened sustain. The Clear-Dot in the center of the head gives the Powerstroke 77 a longer life and an excellent response from the center to the edge. The only difference between the Powerstroke 77 Colortone heads and the conventional version is that they are colored; the sound remains the same. Perfectly suitable for color accents in stage sets – for example with acrylic drum sets.
