Phil,
Don't forget to go to W 48th St. right off 7th Ave in Times Square and visit Manny's, Sam Ash, We Buy Guitars, etc. on music row. A visit to Manhattan is not complete without stopping there for a minute or two, to pay homage to where Hendrix used to buy his Strats..I'm sure the wife will understand.
When I lived in NYC, I worked at Martin Audio in midtown (the Pro audio center of the universe) in their technical services dept. I would regularly run over to W 48th St on my lunch hour to hunt for guitars for my growing collection. Almost always saw a well know musician or two while browsing... I'll never forget standing next to the late Rory Gallagher.. both of us buying picks at Manny's and thinking...holy cow is he short! Little Irish cat about 5'5" tall.
