In 1970 “SIGMA”, the brand name 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 and shipping to the music stores. “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.
The company AMI feel committed and obliged to this tradition. As a distributor of fine acoustic and classical guitars for over 25 years, it is a great honour that we were able to obtain for some parts of the world the rights of the time-honoured name “Sigma Guitars Est. 1970” as well as the distinct Sigma logo.
