This is a 22" Brilliant Series Ride Cymbal from Koide Cymbals. This particular cymbal is their first 22" Brilliant ride, and it is a prototype. It weighs 3,016 grams.
It sounds limpid and straight, like seeing the water ripples on the very quiet pool.
It has such a wide open brilliant trebles that sustains divinely. This is definitely the one of the kind cymbal sound. I have never met anything like this cymbal before.
KOIDE cymbal sounds different from any other cymbals because of the bronze (the raw material of cymbal) that they use. Koide Cymbal uses the cymbal blank that is made in a new way, which was invented by the collaborations of the following research groups;
1. Osaka Alloying Works, Co., Ltd.
2. Japan Atomic Energy Agency
3. Industrial Technology Center of Fukui Prefecture
4. University of Fukui, Vibration and Acoustic Laboratory
5. Koide Industrial Co. Ltd.
Koide teamed up with these highly technological Japanese metal producing expert groups to create their cymbal blank. Their new technology allows them to freely blend the elements of different kinds of metals into their bronze, which was not possible before with certain elements, like Zirconium.
They have been experimenting the influence to the cymbal's tone and length of sustain by mixing different metals. They say that they are working with B24, B23, B22, B21, B20 with Titanium, Zirconium, Iron, and so on.
Well, I am not an expert in metal, but I just love how KOIDE cymbals sound.
