Trinity Heavy Series B20 Cymbals are all hand hammered, B20 cymbals in the 1,000 year tradition. Made entirely by hand from the alloy to the final tuning, the Heavy Series have a big, powerful tone with dynamic harmonics. Each of these handmade cymbals has a unique voice. They are hand lathed on the bottom for excellent tuning, the left raw on the top with only the bell and edge lathed. This gives each cymbal a powerful raw tone and a uniquely musical voice. People say they sound amazing. We just say they're Heavy.
