Heavy, unlathed, air-vented bottom boosts power and crispness for increased clarity and precision. The unique design of SABIAN 13" HH Fusion Hi-Hats also helps eliminate airlock. SABIAN introduces HH Remastered – with more hammering, more complexity, and more tone. As a result, HH Fusion Hats deliver faster responses and warmer tone. Much like a remastered classic album is taken from the great to the sublime, HH Remastered adds complexity and tone to each cymbal, delivering unmatched sonic texture across the entire line.
