This is exactly what I should do, great advice. I haven't really delved much into this stuff, maybe you could give me some advice/suggestions?
Okay, it's hard for me to be specific here, because I am so used to doing these things that when I hear the song and a certain effect is not there, I instantly perceive it as "missing", haha ... so going through the whole song would be a bit overkill.
Try this though:
Set up the following vocal tracks (use sends so you can EQ the returns):
1: clean with a very small reverb (like they are now)
2: with a flanger on a setting you like
3: with a 1/2 delay
4: with a 1/4 delay
5: with a 1/8 delay
6: with a chopper effect set to 16th notes
7: with a phaser
8: with a chorus going into a long church-like reverb
9: with a telephone-eq setting
Now go through the song word by word and just cut pieces that make sense as a "logical unit" - then put them into one of the channels and find out which effect you like. This may be some work at first, but very soon you'll be able to imagine how it will sound and be quicker.
With the tons of different vocal styles in this song already, I don't think it will be necessary to change the vocals too much, but to have a little effect on some of the phrases would provide an added kick, I think.
On my song "Storm/Sparks/Structure" on my last album, I decided to have 4 effects set up and cycled through them all the time, so on 3 words of a phrase you'd have a flanger, and on the next 5 you'd hear a chorus, on the next 4 there was a chopper, etc. ... The song is about emotional unrest and I wanted to create something strange going on in the vocals, where subconsciously something was always happening. It worked really well, because you don't really notice until you listen closely - but if I switched out the FX it sounded completely boring.
Try the above method and please post the results!
