Sigma guitars are hard to precisely date but I believe this one to be an early 80’s example in great condition made in Japan. This is one of their higher end models and it sounds like it with bright clear tone. The guitar has a new bone nut and strings, the action is low and it plays beautifully. There’s a high gloss finish with only a couple slight dings on the sound board and a small finish scratch on one side. The photos show it all but please contact me with any specific questions.
