I've been searching for a bigger sounding vocal for a long time. Doubling is effective, but it's not always the effect I want. What about the verses that I don't want chorused sounding?
Personally I've found that pushing the compressor a little harder makes the vocal more up front and in your face. You can even lean toward limiting (high ratio). I remember hearing a friend's vocal recordings and asking him how he got such a great sounding vocal - he said he always puts a limiter on it. That can be a bit extreme, and you certainly kill your dynamic range, but when I tried it, it gave me more of the present, in your face, dramatic vocal than the $1,000 mic I bought last year.
