We have a PAiSTe Formula 602 Heavy 20-inch wheel, believed to have been manufactured in 1974! [Formula 602] The FORMULA 602, handmade by skilled Swiss craftsmen using the legendary CuSn20 alloy (commonly known as 602 bronze), was released in 1959 and became highly popular with many drummers due to its clear, soft, and delicate sound. Production ended in the 1990s, but has been resumed since 2011. The volume is perfect for precise playing, the touch is delicate and soft, and the sound is clear and acoustic. It offers new cymbal sounds to drummers who are familiar with the sound of that time, as well as those with no experience. <Heavy 20> This is a multi-purpose model that can be used for crash riding. When playing legato, a medium-pitched ping sound is heard along with mid- to low-range overtones, and the cups produce a high-pitched, clear sound. It can also be used as a heavy crash cymbal that produces sufficient volume. Size: 20 inches Serial number: 431285 *Please note that this is a vintage item and may have scratches, dirt, rust, etc.
