In 1970 “SIGMA”, the brandname for acoustic guitars, was launched.
They were built by specially trained staff in the most efficient guitar factories in Japan and then sent to the US for inspection before being released for sale to the music stores.
The first Japanese made Sigma guitars were quite different to the instruments built in the following years in other countries. After several years of production the manufacturing of the guitars was moved to Korea, with new model numbers in place, and the development of a new logo.
From now on every single guitar featured on the headstock the following words with pride: “Sigma Guitars Est. 1970”.
Sigma Guitars ”were soon to have an excellent, yes even legendary, reputation". Some models were said to be of outstanding quality, both, in construction and sound. That’s why it is striking, but not surprising, that there are hardly any second-hand Sigma guitars up for sale. Most owners still swear by their instruments and would never part with them.
