I read the linked article, and it seems to be that the music industry in general is in financial trouble.
Steinway, Fender, and Guitar Center are all in debt up to their eyeballs.
Makes me think that their managements have not been steering their ships correctly. Taking on debt as sales drop is not a formula for business success.
But a default will usually result in selling off parts of the business in a restructuring deal, not a shuttering of the entire business. Especially if parts of it are actually still profitable.
