tips on hi hat lines

[dirty_bass]

Hmm, I think I know what you are looking for.
I`d suggest a very subtle bit of bit crushing or some harsh wave shaping, with the eq inserted after the effects and maybe a little top boost.
I wouldn`t advice compressing the hats at all, leave that till the mastering stage.

You might be talking about the schranze style of "fizzy" hats? which in that case, a touch of distortion, some overdriven sidechain compress.

yeah im not on about shranz style hats. just the kinda hats the feature in quit e a few techno tunes.

very percussive and make a good loop when they r playing on there own.
