Operating in its current incarnation since 2004 after creating a headquarters in the United States, Istanbul Agop is one of the cymbal industry's leaders in crafting traditional Turksih cymbals. The company was founded by and named after Agop Tomurcuk, who spent decades in Turkey's sole cymbal foundry learning the craft before creating his own company.

Designed after Agop's death to the specifications of a notebook he kept for years, the Signature series is a distillation of decades in cymbal-making down to Agop's favorite qualities. The cymbals feature raw lathing and a green logo stamping because it was the founder's favorite color.

Built with a depressed bell, the Signature Flat Ride features the darkest timbre in the Signature series with an easily controlled wash.
