02 The Engineer Sound engineers can be notoriously difficult to get along with.
They work long hours and don't always get paid for them all!
"Find an engineer you can communicate with."

Plus they think they're geniuses (only joking!).
Seriously though, the main thing to remember is that without good communication between you and them, no track will get created.
Keep things friendly but at the same time, if you feel them taking over and not working to your instruction maybe a gentle reminder that you're paying your hard earned might be in order.
If there's a particular track that you like and you want to get a similar sound, bring along the CD or vinyl for the engineer to use as a reference.
It's better than trying to describe it to them while the clock's ticking or having them spend time trying to give you what you want but ending up with the wrong feel.
You'll lose confidence in their abilities and they'll think you don't know what you want.
