Over the past few years, I've seen many, many drummers stacking cymbals. Splashes on chinas, crashes on crashes, etc... we're not talking a few inches apart to save on stands, I'm talking the sound of stacked cymbals.
Who here does it, and with what? I've been fooling around with the concept lately and have had both successes and failures. I have a healthy collection of old and cracked cymbals, and my favorite so far has been a 17" crash on top of an 18" crash. Just washy enough, but more of an employed accent sound.
Though I've heard many stacked sounds (especially from Mike Portnoy), I'm not sure what I'd want to go with. What do you guys use, and in what genre/ capacity?
