The K EFX is a darker version of the A Custom. This special effect cymbal features a unique laser "cut out" design that creates a dry, trashy sound, with sudden explosiveness and quick decay. Crash it for heavy, punctuating accents, or stack it with other cymbals to explore even more articulations, colors and effects. K EFX cymbals come in a traditional K finish and thin weight.
