Thanks, John,
Believe it or not, I got on Behringer's site and they have a section where you can submit an FAQ so I submitted my question. Voila! They responded right back and told me that all I have to do is turn up the FX knob on the mic input and turn it down on all the other inputs! It is that easy! I'm really glad that I bought the Behringer now... they have awesome service after the sale.
Thanks again, John. I'll let you know how the guitar sounds through this system.
