Yes, Best Buy is in the musical instruments biz now. Not sure if all stores are participating, but mine has been stocking guitars, basses, amps, drums and P.A. stuff since last summer.
Major brands (Fender, Gibson, Ampeg, etc.) which surprised me but pricing at this one at least is nothing special... usually the same as the GC up the street. I haven't quite figured out what Best Buy's angle on the whole thing is, yet, since they don't really seem to be differentiating themselves on either merchandise or price. And frankly, I'm not sure how well they are going to do considering we already have a GC and two local shops to service an MSA of maybe, 200,000.
And the joke here anyway is that they can't be considered a "real" music store cause they don't have a bulletin board up
