Mark, if you have a bullfrog voice such as mine, no simulator on the planet will work effectively.

Now, I agree that finding a good, reliable, female singer to work with you is damned near impossible, at least from my experience. My daughter has a fantastic voice, but even splitting the proceeds in half with her, it was still not enough money for her to make a living. And, she really didn't enjoy being on stage. Consequently, she only worked with me for about a week, my convalescent time after eye surgery. When the docs gave me the go ahead to begin lifting again, she went back to being a full-time mom.

Good luck,

Gary
