Man, I only wish I had experiences like that from childhood or my teens. Sounds wonderful.
I moved around a lot as a kid, mostly in smaller towns, and the small music stores of my youth were overpriced, understocked, and staffed by either grumpy old kid-haters or (near the slightly larger towns) snotty frustrated rock stars.
Everything of second-line quality and full list price.
Great places to find the Hondo Strat copy of your dreams for $375, or a set of slightly rusty electric strings for $7.95. Pair of bowed Pro-Marks for $11.
They basically made their money on parents buying their kids' first instruments. Either band instruments or holiday present rock or folk instruments. If you walked in there and they sized you up as someone they could not definitely make a big sale to that day, you were either invisible or watched like a hawk like you were going to break or steal something.
Forget being able to try out instruments unless you could convince them that you were ready to choose TODAY from their (invariably meager) selection. You want to check out a few instruments, then go home and decide which one you want to save up for, or tell your parents which one you want for Christmas? Don't waste my time.
I still remember taking a trip to Atlanta with my mother in the late '70's, and we happened to pass by a store (probably like the ones you all are talking about) that actually had real Fender guitars for sale, and I took a look at the marked prices and thought I was dreaming. My mouth literally came open; I just could not believe how reasonably priced these instruments were, and actual Fenders, like the guys in the magazines played, not Univox copies of Fenders.
Hearing about these places that were nurturing community music centers always just amazes me. Sounds magical. Where were they when I was growing up? Larger towns, perhaps, where there was more money?
