If you hire a studio with a professional engineer, you expect the guy:
- to be able to handle, and know all the technical stuff regarding that studios equipment.
-You also expect him to be skilled in micing(drums, percc, piano etc.)
-And to come up with technical solutions that benefit the project..
and so on, and so on....
Now, this needs to be a pretty skilled person, And my experience(its not that much:-) is that when dealing with engineers that have some form of engineer school degree as the prime background, they often don't have "it".
They tend to tell you" you cant do that cos the freq 20- to..."etc
And things go pretty slow
But when working with souls that have a broad practical background, and have figured things out for them self, well.....they work fast, and urge you to try new things out etc etc...
My point being is that people with the right drive, i guess whether they have gone to engineer school or not, gets to "know the secrets" of being a professional engineer cos they are consumed by it...
A diploma might impress some people, but you need engineers that can deliver..
Having said that, I know a guy I studied with in L.A in the early 90 s, who DID study to become an engineer.
He has mixed & engineered with some big artists, and this summer he mixed a number one, hit record across the globe, with a new U.S band.
Oh, but he also worked his ass off in "The Village" in L.A eight days a week besides going to school....
