Since the Omni can't handle all my Input needs I have decided to purchase a Behringer UB 1202 mixer. I first thought I would just use the Behringer to handle the extra modules I had. But now I wonder if it would be better to plug all my instruments and Mic into the Behringer then go OUT of the Mixer into the Omni? Or still have my Mic and Guitar(with Pod XT)Plugged into the Omni, while everything else is in the Behringer?

The UB 1202 boasts on having Great Mic Preamps. Are they better/worse/same as the Omni Pres?
