Felder never had a great voice, but I think it's better now than it used to be. Still not a natural talent, it sounds tutored and doctored here, true.
I believe more people use autotune nowadays than we all think - and not just the usual suspect pop-dance acts. It's just hushed up. A while ago, I read an interview with Halford where they asked him whether he used autotune on stage and he frankly admitted it: "Not a lot, a quarter note, everyone does it these days, it ensures consistency on a long tour, you are not as good as you wish to be every night". And Halford never had issues pitching. OTOH, when I hear the recent Van Halen live CD, some more autotune might have helped (both Dave and the listeners)!
Or quite possibly not.
