The Istanbul Agop 17″ Traditional Dark Hi-Hat Cymbals (DH17) feature a darker, lower pitched and more controlled open sound with a fatter, softer closed sound. The Traditional Series is where it all began for Istanbul Agop Cymbals. Traditional Series Cymbals are completely lathed on top and bottom, producing rich, and warm overtones and a highly musical presence. They are available in weights ranging from paper-thin to heavy, offering a wide array of choices to complement any style of music.
