Vintage Martin Guitar

Up for auction is this early 70s DM-5 acoustic guitar in good condition. Getting harder to find in playable condition. This guitar has a nice folk kind of sound to it. You can go to youtube and see a demo of a DM-5 like this one. Just type in sigma dm 5. I believe his is tuned a little different or has heavier strings than this one but it will give you an idea of what this baby is capable of. Has a good strong voice and is fairly easy to play. The neck looks good to me and the tech at Mundt Music in Tyler Tx. said the same thing. This guitar is in overall great shape for its age. Like any old guitar there are nicks and scratches but they are minimal on this one. I just got the camera I used here and I think I got too good of a camera. It shows things I never even noticed before so take into consideration if you can see fine particles of dust the flaws are also greatly embelleshed. The nick you see on the top by the pick guard is hardly even noticable except upon close inspection. They got a little happy with the varnish which you can see on the bottom of the guitar. I believe everything is original on this guitar. I will copy additional information to the end of this ad. Sorry no case. Shipping will be a flat rate of $40.00 anywhere in the lower 48 states. We ask to be contacted within 3 days and payment be made within 7 days of close of auction. Feel free to ask Questions before bidding.

Sigma guitars made in Japan from 1970 through 1979 can be distinguished by a headstock logo consisting of the single word SIGMA surmounted with the ? symbol (the Greek letter sigma), in mother of pearl. The sigma symbol is often described as a "sideways M." Interestingly, while playing a Sigma guitar the "sideways M" becomes "right side up" suggesting "M" for Martin.

Sigma classical guitars do not have the headstock logo, and one must rely on the inner label for identification.

Made in Japan Sigma's (1970 through the late '70s) had an inner paper label giving model and serial numbers. "Sigma Serial Numbers do not provide an indicator of the year in which a particular model was built. However, most Sigma models were offered only for a limited number of years, so that most models' construction dates can be narrowed down to a reasonable range."[3] For example, serial numbers on the earliest DR-7s start with 4 digit numbers on through 5 digit numbers. One Sigma DR-7 owner stated "I have an old Sigma DR-7 Guitar....s/n 6860. Bought it new in 1970."[4] Further, DR-7s with a four digit ink stamped serial number and a zero fret strongly suggests a very early build date. Later, early 70's Sigma guitar serial numbers started with 7* suggesting the 197* build date. "Sigma Martin USA" guitars built in the early 80's had serial numbers 900,001 to 902,908.[5] Serial numbers for Sigma guitars built in Korea and Taiwan are perhaps meaningless
