Mike Robinson, Director of Marketing for KHS America, explains the new Mapex Soniclear bearing edge and how this will help you to play more. The Soniclear bearing edge helps fitting drum heads right away without rocking. It also increases the contact between head and shell. This gives you better control of the overtones and it transmits more energy through the shell which results in more shell resonance. Now drummer can spend less time on tuning and play more.
