Zildjian K Constantinople cymbals speak with the dark warm sound associated with Zildjian cymbals made in Turkey in the first half of the 20th Century. "Old K's" first resurfaced during the 1950s and 1960s in set-ups of bebop era vanguard drummers like Elvin Jones. K Constantinoples are hand-lathed by skilled artisans using old-style cutting tools. Pits and other surface impurities, that modern finishing processes remove, are retained, preserving the original tonal quality.
