You asked for it, you got it!  Brand new Constantine Cymbals Clap Stackers consists of a 10", 12" and 14" flat cymbals with FX holes drilled in, curved over and mounted together resulting in a fast metallic "clap" sound with just a hint of "trash".  If you need sound effects, this is for you!  
 
This is the Natural FX style.  We also carry the Clap Stacker in Classic series without FX holes for the traditional "clap" sound.
