You as the Artist, Producer, or Label have a vision for your music. As your mix engineer, it's MY job to ensure your vision is best relayed to that audience. The quality of that job isn't determined by the having the most expensive plugins (although it IS essential to have proper tools) or the newest, coolest studio gear. When looking for a mix engineer, remember THIS above all else: You are paying for a mix engineers OPINON. Now, for me- that opinon is based on a couple things: MY experience and YOUR vision. This is why I am such a fan of communication. I TRULY want to understand your music, who you are trying to reach, what YOUR message is. Once I understand where you're trying to go- I assure you I can get you there.
