Specialty effects cymbals, such as stacks, ozone, and perforated designs, create unique textures beyond traditional cymbal sounds. These innovations emerged in modern rock and experimental music. Key models include Zildjian (EFX Crash), Sabian (HHX Aero Crash), Meinl (Trash Stack), and Paiste (Noise Works). These cymbals offer distinct percussive qualities, from white noise-like sustain to gated chokes, expanding sonic possibilities for creative drummers.
