A: We understand we need to work harder and provide better products in order to be recognized as a serious drum brand. We studied different drum making technologies and came to the conclusion that the drum’s acoustic and physical performance begins with well-designed and carefully manufactured drum shells, specific bearing edges combined with the appropriate mix of drum heads. For instance, understanding that the purity of the acoustic shell decides the purity of the sound projection, we adopt an additional process of waxing the shell’s bearing edge and inner the shell itself , providing ease of tuning and a superior sound projection. Of course, we focus on developing more necessary manufacture process to continually refine our drums.
