Just wanted experiences or opinions of this online retailer. Recently I made two separate purchases from them and was quite pleased.
I haven't purchased anything from Musician's Friend for close to 15 years or so. So my opinion of them isn't very current. I recall finding their service and prices to be "adequate", but nothing to get excited about.
For at least the past decade, my go-to online music gear retailer has been American Musical Supply. In my experience, their inventory has been every bit as good as Musician's Friend, and their service probably better. And since they're just on the other side of the Hudson River from me, I receive my purchases within one (1) business day via UPS Ground - as opposed to nearly one calendar week from Musician's Friend.
That said, all of the major online music gear retailers tend to specialize in brands that are toward the lower end of the price/value continuum. So if my tastes run to anything higher end than Hartke or Squier, I've gotta go elsewhere anyway.

In recent years, I've found both Amazon & Sweetwater Sound have been able to fill that gap rather nicely...
