My AOA is actually really wide. Although as I've gotten older, my AOA has also gotten older. I used to be very attracted to 9 to 13 year old boys, but now I'm less attracted to the younger ages and more attracted to young teens. Even older teens can catch my eye now and EVEN young twenty somethings. Anyway, I've never heard of a morphvox voice changer but I am kind of familiar with vocal processors. The thing with a vocal processor is that they never seem to sound real enough, at least not to me, anyway. And I think a little bit goes a long way when using them. A friend of mine has a bar band and the singer is convinced that the processor is the holy grail answer to all of his vocal needs. I swear when he uses that thing he has so much of his voice being processed that he sounds like Mickey Mouse. It is horrible. So shop around and see what you think. It MIGHT help your vocal range, but the best thing is probably always the natural way of doing things. Especially with vocals. That is just my opinion, anyway. They have a bunch of vocal effects to check out at Musician's Friend.
