They're the Asian import versions of Martin, sort of a Squier-Fender relationship, but not as awesome.
They're decent, from my experience. Nothing special, but also not garbage

The old ones were made by Martin overseas. They were actually very good. All were made to Martin specs with Asian lumber. The country of origin changed over the years. Recently the "Sigma" name was purchased by a German company, which started making them again. I do not think there is any affiliation with Martin any more.
