Try using an EQ to cut before a compressor and an EQ to boost after. This way frequencies won't be in the mix so it won't affect the compressor.

EQ or compression 1st is a big topic of debate.

We suggest EQ before & after! Using an EQ to cut before the compressor will help the compressor respond better because boxy & muddy frequencies you don't want in the mix won't cause the compressor to react & only the frequency you want to pass through the compressor will affect it.

It's usually a good idea to add another EQ to cut after the compressor as well. The compressor will introduce some new harmonics & tones, so cutting those frequencies out too will help reduce some unwanted tone.

Adding an EQ to boost is usually best after the compressor as well because you will be boosting the signal in some areas & if you boost before the compressor, those boosted frequencies will cause the compressor to react & can create a pumping feeling sometimes. Applying boosted EQ afterward won't cause the compressor to react.
