Remo 50 Series pre-tuned Tubano drums are an excellent option for your music classroom, therapy session, or virtually any drumming situation! They feature a Skyndeep head for an authentic ethnic drum sound. However, the tone of pre-tuned Tubanos can not be changed, so several drums of the same size may have slightly different pitches. The Remo 50 Series Tubanos also feature an Acousticon shell that is made of 99.9% recycled wood materials. This means that they will withstand climate changes, exuberant playing, and will be a long-lasting addition to your percussion collection
