A beautiful 1978 Sigma Martin DR 12-7 Dreadnought 12 guitar and original Softshell Case. Made in Japan!

This guitar is in fantastic shape. Just superficial Dings and normal playing scratches. Its beautiful, fresh new light gauge strings and a Pro Setup. It plays as nice as it looks. Easy playing low action with no fret outs and what a sound!!

These guitars were made to Martin Specs in 1978. It’s a Transition year that sent the guitars from Korea, this one, to Japan. You can tell it’s a Japanese, higher quality made guitar by the stamp in the back brace. Made in Japan for CF Martin and Co. They only did that in 1978. The Model number stands for D= Dreadnought, R= Rosewood, 12= 12 String and 7= the quality of the woods used. This guitar has a laminated Spruce top, Laminated Rosewood back and sides and the cool Rosewood Laminated Headstock Logo. The high quality Rosewood laminate is so dark it almost looks black..Very cool! The Ebony fretboard is very nice and the frets are hardly used. The nut measures 1 15/16ths and it has a 25 ½ inch scale neck. Very high quality for a guitar that remains very inexpensive for what you get. Easy playing action makes this a great guitar to start on or an extra to have along if you don't want to bring your expensive Martin!

Still wondering how we dated this guitar?

Here’s some info we found on the web regarding these cool Guitars…

The first Sigmas were typically dreadnought acoustics, although Grand Concert Series (GCS) and classical models were also produced from the early 1970s (1971?) onward. Though other models were produced the most common two throughout the '70's were the Dreadnought models DM-5 (DM12-5) and DR-7 (DR12-7.) D for dreadnought, R for rosewood, M for mahogany and the number denoting the grade of wood, 5, 7, 9, 11, 15.

Construction moved from Japan from 1970–1983, to Korea from 1984-1994, to Taiwan in 1994 (made in both Korea and Taiwan for the 1994 model year) and finally Indonesia (?–2007).

In 1978, model designations were added to capitalize on Martin model numbers: the DM-18, DM-19, DR-28, DR-28H, DR-35, DR-41, and DR-45. They are called 'Second Generation' Sigma's by C.F. Martin and featured solid wood top. The "First Generation" DM-5 and DR-7 (laminate wood bodies and tops,) as well as other early models (e.g., the GCS-7/CS-7) remained in production during this time as well.

By the mid 1970's (c1976) the headstock logo design changed to a gold "Martin style" decal that said, "Sigma Guitars" in script with "Est. 1970" underneath in a smaller block font. The headstock shape was also modified to a deeper taper and shaped to resemble the Martin instruments.

The Back Brace Brand: From 1978 through 1983; 1978 being a transition year, one might find the center back brace is pressure stamped, or "branded" in a football shape stating Sigma Guitars/Made in Japan/For/C.F. Martin & Co. Being a mid-year change, some continued on with the "Purple" label, though with the new serial number designation preceded by an "S" or an "E" This is prefixed by the serial number assigned to the instrument and followed by an ink stamp of the model number. (e.g. L-R as seen through the sound hole: Serial number, "Brand," Model number.) The serial numbers on these instruments were often preceded by the letters S or E; e.g. S0XXXXX. It is currently believed that this transition was complete by 1979.

Check out the original case we have with this cool guitar. Its in great shape, like the guitar. All latches, hinges and original handle are present and working. Any check out the beautiful Gold Plush lining! Wow, the guitar looks great in there! What an awesome guitar outfit for you!

Sold as-is no returns as its used and vintage…However, I have been hand-picking vintage guitars for my customers for over 20 years now and they have all  loved the guitars I found for them…This one will certainly not be an exception.

Thanks for checking out our cool guitars.
