Here is a really sweet Sigma Martin made in the mid 80's with a faded pink label designating the country of origin as South Korea. Martin originally started Sigma in Japan in 1970 and then in 1985 moved operations to Korea. The guitar is a 24.75 scale with 20 frets. The neck joins the body on the 14th fret. The action is very good and can be easily fretted anywhere on the neck. It has an adjustable bridge which I haven't touched as the action is as good as it could be. The neck is a "soft" V. Spruce top with rosewood bridge, mahogany back and sides, unbound rosewood neck. Shipped on a sturdy hardshell case. This guitar compares closely to a Martin 00-18. Why spend thousands??? The guitar is in excellent condition albeit a small intrusion on the side upper bout which I've shown in my photos. I'll do my best to answer any questions! Thanks for looking!
