Rikki, my thoughts.

1-I would buy an inexpensive mic.

2-Learn how to use the TC Helicon. (If my memory is correct you have a Korg)

The TCH does a lot more than adding voices. If I use my mic directly into my Bose it sounds good – but no comparison when it goes through my Voice Live Telicon. Reverb, delay. Doubling your voice, and even pitch correction. Learn about the different parameters of the unit; which I know you do well – Then if it sounds fair-to-nice, buy the best mic you can afford. Amen!

PS, After doing all the above, and you book any paying jobs (because of your singing) it would be nice to give about 15% to the guys on this forum Ha Ha
