The Yamaha PCY135 is a 13" round cymbal pad. This cymbal pad is very sensitive and responds with a natural swinging motion when struck. The PCY135 is a triple-zone pad, so three seperate sounds can be assigned to the pad. You can assign this extra cymbal pad to control an extra crash cymbal, splash cymbal, china cymbal, cowbell, woodblock, or any other sound included in your drum module. The only limitations are the number of extra trigger inputs on your drum module (most kits leave you with at least two), and the physical space on your drum rack.
