The 15" Istanbul Agop Traditional Dark Hi-Hat Cymbals are the thinnest of the Traditional Series Hi-hats. A darker, lower pitched and more controlled open sound with a fatter, softer closed sound. Each Turkish cymbal is a work of art hand-crafted individually by the cymbalsmith. Variations in color, hammer marks, lathing, labels, etc., are all enhancements that add to the natural beauty, sound, and unique quality of these one-of-a-kind cymbals.
