When tracking split the signal after the mic to different pres.
When tracking to tape use 2 or 3 tracks with different saturations distorsions, then mix to mono to taste.
On mixdown split the the vocal in two channels and compress with different comps and settings, say 1176 and a la2a, mix to taste.
I'm hoping to see a long list of actual effects folks have used on vocals ... that would serve as a place to visit if you're stuck.
*slap L/R detune L pitch and delay shorter time
*short plate with damped highs (actual plate) plus tape slap, etc.
I thought of you right away, in that people with great experience in Effectland may feel this is giving away secrets, but I hope you'll all chime in anyway as it's about the subtlety and timing, not the concept. thumbsup
Did this for a vocal intro once..
Blasted a solo vocal through a mono pa speaker on a second floor building across a bustling street..downtown LA..
2 mikes street[across] level recorded to stereo 30 feet apart .
Way cool..didn't make the mix.. the label didn't like it[bunch of Pussies!!]
Split the vocal, reamp through a low wattage guitar combo amp (with a small speaker(s), Distort the the amp, mic it, bring it up on another track. Then adjust to the EQ of the amp'd vocal to compliment the "clean" vocal.
