This is where the Zildjian Sound Lab goes into innovation overdrive. K Customs arm you with a collection of modern K voices like no other. In this range you'll find sounds that set the standard for modern cymbal design. Whether it's the warm shimmering tones of a Ride cymbal, or the complex sizzle of a pair of HiHats, these cymbals all create a uniquely beautiful sound. Sound: Unique pairing, modeled after Steve Gadd's personal HiHats. The HiHats feature a slightly undersized (13 15/16"), medium weight top cymbal and a medium-thin bottom cymbal.
