Mostly a series of equalizers, and volume control. The amp provides amazing volume control (not much distortion even at high high volume) so I pull it back a bit before sending it through. I have different equalizers so I can turn on and odd discrete passes based on the music. AH's ability to send the sound across multiple output paths is also really nice and I use that (less often) as well.
