13" Zildjian A Custom MastersoundZildjian site says:
Featuring the same crisp, rich and colorful sounds associated with the A Custom range, but with a bolder and full-bodied overall sound. Hammered grooves in the bottom cymbal rapidly vent trapped air for a fast and clear "chick" sound.
I say:
based on my humble experience and opionion; comparing it with other hihats i've used (im not gona mention the models coz u might hate me for it): the sound is bright, not muffled, non-dull, doesnt sound like a clunky piece of branded metal; controlled volume depending on your dynamics and not scattered everywhere once hit unlike the 14 a custom mastersound, chick is clean, clear, non-dull coz of stick definition, and this is still apparent even when the hats are tightly closed; the sizzle when driven open gives a clean, modulated tone, non-dull. in short it retains its brightness in all ways it's hit. i think it goes well with rock, pop, rnb, samba, etc. jazz? i dont think so, well as far as im concerned, i dont do jazz anyway, too hard and i cant be bothered.
