If you don't wanna run another head unit with a tuner, you could always do what i've suggested to a few other people and buy a really cheap Rat SHack handheld/jogging radio, and get a mini-plug -> RCA wire and just plug the radio into the aux in of the empeg. Just leave the wire in your glovebox (and the radio i guess). Much cheaper than buying a $300 tuner on ebay =]
