I've been here a couple of times to buy oboe reeds - the staff is always really helpful but they don't always have what I need - therefore, I'd strongly recomment calling before stopping in; they're always happy to order things but their selection focuses more on breadth than depth (though I imagine for popular instruments like guitar they have everything you could possibly need). Staff is very knowledgable and pleasant. Note that the store is now on Arch between 10th & 11th (used to be nearer 8th st, hence the name). And I second the earlier reviewer, parking & traffic are hellish down there, particularly on weekends - walk there if you can.
PROS: Helpful staff, able to get anything (though may take a few days)
CONS: Traffic/parking a challenge
