The Powerstroke® P3 Classic Fit Drumheads provide a larger inner diameter design with a narrower flesh hoop and step design to address older vintage drums that are out of round with thick overlapping drum coverings. Vintage Drums that have a thick overlapping seam will interfere with the drumhead ?esh hoop, keeping it from moving down over the seam and not allowing the drumhead ?lm to rest on the bearing edge. If the standard drumhead is forced over the shell it will not resonant freely and cause wrinkles in the drumhead ?lm. Classic Fit Drumheads provide a solution to these issues providing a specially designed head that allows proper fit, seating and tuning for even the most challenging vintage drums.
