When I was a "kid" I had the priviledge of frequenting "Midwestern Music" on Gage Ave. in Topeka, Ks. Owned & operated by a great man named Cecil Baker and his family (son Larry was an original member of "Kansas"). It was just what you've all been talking about.
Moved to Hays, Ks to go to college. They had a family-owned music store named "Hays Music." Run by the Meckle (SP?) famiy. Another great place. One of my best friends (band member and sang at my wedding) repaired instruments there and I was in-and-out of there as much as I was the above.
Most of those places, even here in Kansas, are LONG GONE. One exception that I know of is Midwest Drum & Percussion in Wichita. I always stop by when we make it that way, and the mgr (Matt J) and the rest make me feel like it's back in the 70s again. So, if you're ever there, make sure you stop by!
My last experience with Banjo Center (in Wichita) wasn't a good one. I walked back into the drum department and basically was ignored by the two HS/College aged kids who where working. They probably wondered what some old **** (gas-passer) like me was even in there for. When I did get their attention and asked them a simple question about a Gretsch set they had on "sale," neither could answer without "looking it up on the computer" (as mentioneded in the original post by steveund). Funny thing -- I figured it out in my, slow, old-fashioned "mind" before they got the answer from the computer... oh well... enough ramblin' I'm sure...
