"The True Touch Training Kit is a revolutionary practice tool that not only offers the low volume required for practicing at home, but also allows drummers to perform critical technique refinement needed to improve their musical expression. The combination of quiet acoustic volume, realistic acoustic touch and sensitive dynamic expression results in a highly satisfying acoustic drum feeling, something that has not been possible with conventional practice kits until now.
