Bill,

I took a listen to a few tracks. The tunnel sound your getting comments on has to do with the effects you are using on your vocal. Try a simple reverb on your vocal. If you want your vocal to stand up front, avoid using too much. When it comes to country vocals, less is more. Hope that helps. Try listening to "The Death of my soul" to see what I mean. http://www.soundclick.com/bands/2/kriskarrmusic.htm
