Hallo from Barcelona, Spain.
all the people have tried my end 80' SigmaGuitars DM2 (or 3, it is not well stamped)n° 232209, made in Korea n° 2, most of them much better player than me, recognized the good sound and quality of this guitar. Recently I started again to play this guitar whith new set of good quality thin cords: it's a fantastic guitar in sounds and aspects. Very proud of the circa 150$ I spent in Italy (my country) at that time, a big effort for a 18 years old guy loking for his first acoustic guitar: so, doubly proud and happy to have found this forum of SigmaGuitars estimators.
Thank to all writers for the precious information I have found here.
