Sigma Guitars
In the 1970s, Martin Guitars launched a series of attractively-priced models under the name Sigma Guitars in order to compete with the growing number of cheaper models being produced in the Far East. Unfortunately, they stopped producing them in 2007 but a German company breathed new life into the name in 2011. With Martin Guitars' blessing, these models are now made in China. They're subject to strict quality controls and everything from the way they're made to the design of the headstock do the original models justice. In short, these acoustic guitars offer the same excellent value for money as the original models did. In the USA, these models are distributed by Martin under the name Kindred Guitars because they no longer hold rights to the Sigma Guitars name.
