Conor McMillan recommends The Music Inn.
Went into the store for the first time today so I could have the jack on one of my guitars mended. The staff I spoke to were nothing but caring and did their best to make me feel welcome with no pressure. While I waited, I tested out one of their guitars and about 10 minutes later, my guitar was good as new at a reasonable price. After today, I think this will be my regular stop for music gear from now on.
