dont overdo effects on vocals
depends on each tune
slight reverb, subtle chorus, proper EQ'ing, lil distort, delays
not too much stereo, except on some parts where you want a certain effect [hooks, etc]
you dont have to compress everytime
also try to eq the reverb itself
if u wanna get creative = lots of possibilities there
distort and pitch bend, time stretch, reverse
vocoders, talk box, assign any knob to automate
lfo, filters, wah wah effect, etc
chop parts, slice, all sorts of yo wtf!
hehe
