Best Guitar Shop in Nashville??

I am in Nashville with a friend who wants to buy her first electric and I want to go to the best shop. She is new to guitar, but she is a multi-instrumentalist and a professional music teacher, so she's not a complete newbie. I'd like her to sit with all the different models/styles, so the place should be helpful/nice and have a good assortment. We wouldn't be looking for an old vintage expensive piece, but I do want to find a used guitar with a little mojo and magic if possible. Any and all suggestions will be appreciated. Thanks!
