I play open handed, so I like to have two voices for every type of cymbal on either side of my kit. I use a 16 over 18 stack on my right side, so I wanted something smaller, higher-pitched and "quicker" on my left. These are perfect for that.
You can have them loose and they have a very cutting, trashy sound to them. Great for accents or for keeping time on in the right context.
Or you can tighten them and have a very quick and crisp note, perfect for playing between these and the hi-hat. Also a really cool sound to use in linear fills.
You can also change the way you stack them for some different sounds, or even change out the splash on top if you want to personalise them a little bit. Experiment and have fun with them.
Being B10, they are very bright and can in some cases be rather jarring. But by the same token, it allows them to cut through loud distorted and down tuned guitars with ease.
Overall they are great accent cymbals or time keeper if you wish to use them that way. They are plenty loud and cut through nicely in the right setting. But they can be a little sharp if used in the wrong context. I highly recommend these to anyone that needs a pretty well priced stack.
