Following the same process used for the last 400 years, Sabian’s artisans craft their Hand Hammered cymbals using just their hands.This takes years of mastery since each blow of the hammer can change the tonal sound of the cymbal, giving every hand hammered cymbal a unique voice. This process gives them a tonally rich, dark, and complex tone, and shadows the days of early cymbal making.The HH Effects Pack offers players a “Sonically Matched” pair, making sure they will sound terrific with each other.
