Are you looking for a hi-hat that sounds old (and looks old), a hi-hat that fills the sound and is able to glue your groove together on the drum kit? Then check out this 15" Holy Grail hi-hat from American Cymbal & Gong.
The hi-hat sits nicely and low tonally. When struck with the tip, you get the most delicious "pearly" attack. When struck with the shoulder, you get a large and full-bodied variation. When you blend these two types of strikes (tip-shoulder-tip-shoulder), you get a really tasty and varied sound into your groove.
Genre-wise, this very dark and crisp hi-hat would fit well with jazz, funk, and vintage rock. But listen for yourself - ultimately, it's something you decide.
