A buddy of mine is a vocalist in a touring band and he is coming over tomorrow to track a vocal demo at my place. I've got my SM58 set up with a cheapo pop filter a few inches away. I use the same mic/room placement technique as I do when I track my guitar tracks, but other than that I'm not sure what to really shoot for short of experimentation. Mic placement to source is another question entirely. I have the vague idea that the mic should be at mouth level and angled upward slightly and should be sung over and not into. Any pointers would be greatly appreciated.
