Product DescriptionRhythm Tech bongos feature a tapered shell which gives them distinctive, crisp highs and warm, mellow lows. The low profile, rounded, ultra-heavyweight rim minimizes the discomfort associated with traditional straight-edged rims. Rhythm Tech Bongos' thin, yet incredibly durable rawhide heads produce greater volume and projection in a wide range of playing situations. Rhythm Tech Bongos have a steel bottom rim that's strong and durable. The rim also provides greater stability to the bongos' tuning lugs, protecting the drum shell while keeping even tension throughout the head. Available in natural oak. Head Sizes: 7" & 9"
