This is interesting... Best Buy getting into the market.... Hopefully their customer service in this area would be as good as the local little guy with better stock availability. My biggest problem with the local music shops is they have very little variety and depth of stock. My problem with the guitar center chain is they're very uneven across their stores in knowledge of the product.
Also, how will Best Buy ensure knowledgeable staff? Will they do Lessons? Rentals? Will have to wait and see.
