Guitar Store not 100 miles away!.
I was pretty bummed when I found out Medley Music in Bryn Mawr closed earlier this year. That left only Philly or King of Prussia for musical instrument stuff of the guitar variety. Discovered Danny's in Narberth across the street from the Narberth Train Station. The shop is run by Dan Gold a personable guy and a familiar face around Medley as he was the rep for Fender. Dan has even performed at the Fest a number of years ago and even though he is just a day tripper at Fest (we won't hold that against him) he knows the scene.
Anyway it's a great little place offering a variey of guitar products and instruments, lessons, etc. This is a business that we should support.
If you need guitar stuff or have some time to kill waiting for the train at Narberth Station, stop in and say Pete the guy from the Folk Fest sent you.
