The most surprising thing about Sick Hats is that if you were to hear them without seeing them, you would never imagine it was a pair of 18" AA's! Thin, and very dry overall - despite all appearances, this is a very controllable pair of hats. Large holes allow Sick Hats to breathe in ways other Hats simply cannot - with virtually no airlock, you hear everything. Think of them as a controllable, pre-EQ white-noise effect. However, if you want more body, with less air in your face, and you want to play patterns without the holes getting in the way, just flip 'em over hole-side down!
