This is a Paiste Sound Formula power ride cymbal. When you think of Sound Formula, most people will think of the 602 series, but this is a different series, only sold for a short time in the 90s. It's quite a niche item, as it's not very common. The Sound Formula series was born in the Swiss factory, the home of Paiste's handmade models. Its all-around character, which accurately responds to all genres, is achieved by using the same The Paiste alloy as Paiste's top brand, The Paiste, and employing sophisticated manufacturing methods. It features a soft, mellow resonance and a bright, crystal-like sound character unique to Paiste. One cymbal can handle everything from soft acoustic playing to loud electric sounds. This is what was written in the catalogs at the time. I found out through research that it was sold at a price equivalent to the 2002 or 3000 series, but in terms of sound, would it be somewhere between the 2002 and Signature series? Some people seem to prefer this one because it has better sound projection than the Signature series. The condition is good, with no cracks or chips. The hole is only slightly deformed, so it shouldn't affect the sound. First come, first served! - Brand: Paiste - Model Name: Sound Formula - Size: 20 inches - Series: Power Ride
