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 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.

The GJA-SG200 is a full scale jumbo sized acoustic guitar. It has the Fishman Sonitone electric preamp installed into this guitar. This model is built with a full solid body topped off with a beautiful autumn burst gloss finishing. Beautiful crowned inlays set into the fretboard to enhance the aesthetic appearance.
