Hey Gary,
Speaking of mikes. Long before I figured out how to use my Digitech with my keyboard I used it quite a bit with guitar. At church we sing through AKG condenser mikes which give a wonderful tone in the lower register. I used to bring my church mike home for the week in hopes of getting some great recordings. The mike was so sensitive that my Digitech would not only harmonize my voice but also the strings on my acoustic guitar. My condenser mike experiment ended when my digital recorder recorded a toilet flush from 2 floors away in 3 part harmony. So yeah, the right microphone is very important.
God Bless,
Don
