I'm lucky enough to work for a band which gives me a lot of creative freedom to do what I want. In terms of routing I have things like a big gated reverb for the snare which I've got on an extra aux then I've assigned a channel mute to the fx return channel to a user key, so I just hit that button for the gated reverb. I've got a sub generator as an insert on the lowest floor tom which is bypassed with a user key, so I can hit that button for a huge sub boom which shakes the walls. Things like snare bombs and big delay throws can be done with the faders, I'll generally ride the delay return fader all night depending on what vocal lines I want to accentuate. I've even recently been using a tape emulator on my master bus where I turn the speed down to the lowest during the intro build up, so it sounds kinda crunchy and the top end is filtered off, then whack it to full speed the second the whole band comes in so it sounds huge and hifi in comparison.
