The R-Series, Low Collar, Fiberskyn® Bongo drumhead provides a superb, authentic drum sound for maximum projection, lively overtones, and slap tones that are easy on your hands. The Low Collar construction is designed specifically to accommodate the various bongo drum manufacturing brands that are equipped with a radius counter hoop rim. This allows for a comfortable playing relationship between the counter hoop rims and playing surface. The design also reduces the amount of torque needed while tuning the drum and minimizes the tuning hook length that may stick out the base of the drum, something that drummers who play seated can really appreciate! Fits full size bongo drums equipped with radius counter hoop rims from most major manufacturers.
