  • Built in Korea for C.F. Martin Co. (import copy of Martin D-35)

Commissioned by CF Martin & made in Korea & constructed to be like the Martin D-35 model dreadnought, this circa 1980/81 is beautiful, with an arrow straight neck & low action. I would list it as excellent condition, I would have listed it as mint, but it has a very superficial graze on the front table, that does not even break the lacquer (See the photo) Has zero fret-wear & no repairs. These Sigma’s are now much sought after & for very good reason, they are basically a Martin D35 made in Korea. The internal braces are branded with “Sigma Guitars, Made in Korea, For CF Martin & Co.

This model has all solid wood construction, with solid Spruce Top & rosewood 3-piece back & sides, rosewood veneered headstock, bound body & fingerboard, bone nut & saddle. Just a gorgeous guitar to hold & play.
