One of the first Grand Concert acoustics to truly set the bar for Martin's performance-level Made in Japan instruments in the 1970s, this remarkably gently aged late 1970s Sigma by Martin GCS-6 Grand Concert Acoustic still boasts low, even action across a rosewood fingerboard, and the notably warm, balanced sustain of vintage multi-ply spruce and bound mahogany construction. The familiar in-hand feel of a solid mahogany neck, original sealed tuners, and a road-ready molded hard case makes this Sigma an easy, accessible choice for touring and session work alike. Notes:
This Late 1970s Sigma by Martin MIJ GCS-6 Grand Concert Acoustic is in Excellent condition, part of a single-owner, climate controlled collection, with extremely light wear consistent with age and occasional home use. Includes fitted molded hard case (pictured).
All instruments from Music Makers are professionally evaluated and set-up in our historic Galesburg, IL. storefront prior to shipping.
