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.
