Did a cover of john lennon's working class hero: pretty amateur recording and performance xD check it out at:
The voice is pretty odd, you supposed to be using an effect or is it just that bad quality-wise? I love New Grounds though, you ever seen Beebo?
Regarding the voice; from what I can hear, you're a fairly good singer. Don't cover it up too much with the effect. Or use it sparingly. I'm working on a cover of All Along The Watchtower with a megaphone effect, but just on one line. How are you recording it? All at once, or are you multitracking it?
