These blocks are a vital tool for percussionists playing intricate Latin-inspired rhythms and drummers laying down grooves on a set. Use them to establish a clear tempo in a marching drum line, and let their sound be heard from across a football field. Their clear sound projects with a “knock” effect that has no harsh overtones or unwanted ring. Their special feature includes a mount that may be re-positioned either at an angle or on one of three sides of the block to allow for optimal placement. The 3/8” mount fits on any standard percussion rod. These blocks are made from high-density PE plastic, so they can be played with anywhere, indoors or outside.
