Haha, used to do mastering, but didnāt use the 303 on other peopleās stuff. I used to run all my mixes through the 303, wtf did I sell mine. Might be the only piece of gear I really regret selling. I still use Vulf comp for Mastering though and itās gorgeous, way deeper, but the actually 303 has some extra pixie dust that canāt be replicated.
