The great thing about Meinl percussion blocks - besides their ability to stand up to heavy playing - is that they are multi-functional. These blocks are a vital tool for percussionists playing intricate Latin inspired rhythms and drummers laying down grooves on a drum 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 ringing. The included mounting bracket may be re-positioned either at an angle or on one of three sides of the block to allow for optimal placement, and can be fitted on any standard 3/8" (9.5mm) percussion rod. These blocks are made from high density plastic, so they can be played anywhere, indoors or outside.
