They are a franchise music gear store originally out of Minneapolis (I've no idea where they are based now). Carry used gear and low end new gear. It's all down to the individual store in terms of the service, but I've never had any problems with mail order from various stores. You can ask for a description on the phone and generally get a decent run through. I've bought mics and outboard from them and everything was as described and working. Every now and then something interesting pops up, but much of their stuff is pretty low end.
Yeah I'm an attorney, but everyone needs a day job.
