I tend to doubt they do that sort of work there. I'm guessing if they take it in at all, they have "trusted" suppliers they can send it to. That's the way it works around here, and this is a major metropolitan area. There really isn't a whole lotta money in musical instrument repair, so it's tough to share it. Unless it's an individual owner who perhaps does the work himself, a retail store's view is kinda "can't live with 'em, can't live without 'em", so they contract 'em.
