A 20" crash with a dark & warm undertone but with clear impact & bright attack!
K Custom is a series of incredibly musical & dynamic cymbals. K Custom has a dark & warm undertone with a large body but still with slightly brighter & more penetrating notes than many models of darker cymbals normally have. The hammering method Zildjian uses here gives the series controlled overtones & a lovely, understated trashiness that doesn't overpower but helps bring out an explosiveness with a quick sortie.
K Custom can be heard & come through the music in a good way but are fast enough that they don't mess up & take up too much space in the soundscape. So you're looking for a model that fits most things but prefers the darker sound over e.g. The light of the A series, then K Custom is something for you!
