Rawhide bongo heads tend to have a warm, deep tone with a lot of nuance layered into the sound. Real skin heads offer a more authentic look and tone than synthetic materials offer, but they are susceptible to changes in humidity and temperature, making them more fragile.
The LP Classic series is a good choice to get an authentic, classic sound out of your bongos. This series is a professional-sounding and professional-quality collection of drum heads for your LP drums.
