Custom cymbal specialists UFIP have "classed" their cymbals into three lines: Bionic, Class and Natural cymbal series. Bionic are high and bright sounding with added emphasis to the higher overtones. These are suggested for hard rock, drum corps or anywhere added power and projection is required. The Class series is a balance between high, middle and lows. These cymbals are said to have midrange articulation and decay with a "shimmer" quality.
