The search for vintage cymbals has finally ended. Like all Bosphorus Cymbals, the Master Series are completely hand made. From the casting process through the final hammering, not one step is relegated to a machine. The alloy is from an ancient formula passed down by many generations of cymbal smiths. It gives these instruments a soft, "played-in" feel. Most importantly, the Master Series are much thinner than today's heavier weighted cymbals. You'll see the characteristic "wobble" made by the cymbal's edge when played. Listen for the woody stick sound and the deep mysterious tone. Feel the dark warm spread underneath. Unlock your creative potential and explore new levels of expression with genuine hand-crafted musical instruments from Bosphorus. Bosphorus Master Series radiate deep dark tone and warm vintage sound. Noted for their soft “played-in” feel and characteristic wobble made by the cymbal's edge, this series has become a mainstay among jazz drummers. The BPM13HH,& BPM14HH Bosphorus hi-hat tops and bottoms are hand lathed as pairs for a perfect match. Both cymbals feature two distinctive lathing patterns on the top with an unlathed bottom. Master Series hats are know for their musicality, providing crisp stick definition sensitive enough for brush use. Dark but ample ‘chick” sound and a warm and full wash when played half-open or splashed. Perfect for acoustic settings.
