Andrew Scheps explains his rule of thumb for EQ placement in the Scheps Omni Channel: should it go before or after compression?
His default is EQ before the compressor, which matches how he naturally works through a channel strip. Since the insert lets you stack two identical EQs anywhere in the chain, you're free to break from that order when it serves the sound.
For drastic EQ moves, he flips the order and places EQ after compression. Big boosts or cuts shift what hits the compressor's detector, so every EQ tweak also changes the compression, making it hard to judge what you're actually hearing.
That's also why the high-pass and low-pass filters live in the preamp section instead of the EQ. It gives you a way to clean up low end before compression even when your main EQ is set to come after it.
