if your EQ is mostly cutting some frequencies, you probably should EQ
first then compress...

if your EQ is mostly boosting some frequencies, you probably should
compress first, then EQ...

but the real answer is it depends on what effect you are trying to get
with EQ and compressing..

the compressor will respond mostly to the loudest frequienceis at it's
input, but will change the level of all the frequencies...
