There are a number of differing views on the order in which to process DX Effects - I tend to use PG Ten Band, PG Dynamics, PG Reverb/Chorus/Distortion etc for each audio track. In the final output channel I use PG Ten Band, PG RTA, Triple Comp, PG Peak Limit. None of these effects, permanently change the Aucio data and can be tested and changed on the fly.
