Lawrence is a bit of a driver from KC. But it isn't too bad.
Midwestern Muiscal Co. can sometimes have some great stuff including archtops.
Guitar Syndicate has a couple on the wall (all new).
I've not found a really good archtop store in KC. The music store scene changed from supporting jazz guitarists to supporting mid-life-crisis beetle-surfer-bands. I wish I was kidding.
