Susan ,
The closest Music Shop that I know of in your State /Area that is well known , reputable and is easily on the same type of level of George Gruhn's Nashvile shop is in NYC .
The shop is called Matt Umanovs Guitars ...
http://www.umanovguitars.com/ I'm from NYC and I have been too his shop many times over the years .
( about 30 years before my move to the West Coast )
Matt is very well respected . His shop is somewhat Boutique in the sense that he has always been one of the go to guys when it comes to tracking down Vintage Martins and a bunch of other high end used guitars ...
acoustic and electric ...
His shop is tucked away on Bleecker street in the heart of Greenwich Village .
Some people (and tourists ) have mixed reviews on his shop because they walk in there expecting The Big Box type of Music Store thing and that's not what he or his shop is all about on any level ..
Bob Dylan and a whole other large group of well know musicians would often shop and buy from Matt because they had built up a solid one on one relationship when it came to purchasing instruments from him and Matts shop offered these musicians a safe haven far away from the Big Box Music Store Insanity
He sells some very high end guitars , a few select brands of mid range consumer type guitars / various acoustic electric instruments and then he brokers and sells for lack of a better term instruments that are unattainable for most people .
Often times some of his best instruments never hit the showroom floor simply because he is a mover and a shaker when it comes to contacting people that are looking for exactly what he may have ...for those type of deals he may do those on an appointment only type of thing ....
Only other thing I can mention about Matts shop is , if your ever are down there or if you choose to contact the shop , deal with Matt directly , not his sales help ....
Matt used to know me by face only , not by name and the few times I ever dealt with his sales help were less that what I was accustomed too ...
Also Rudys Guitars is a place to consider ...NYC
Rudy has a large collection of guitars in his personal collection , he also carrys a whole long list of instruments in his shop , even makes his own brand and his clientele includes Iconic Players
If I ever hit the Lotto I'm gonna buy one of his
Vintage D Angleico's ......
http://rudysmusic.com/ same advice goes as before ....talk to the owner Rudy
Anyway , I've flapped my gums long enough in the breeze over here ...good luck ,
Kenny
