I bought a Martin Sigma DR7 in my youth in 1978 brand new in a music store. I wrote hundreds of songs on that guitar through the years, took it on the road through all types of weather conditions, took it in the studio. Always loved the sound, loved the simple look, loved the reliability and integrity of the instrument. Love the recorded sound - great transparency with great presence low to high. Now I have acquired 2 more DR7's on the used market. Though I own much more expensive guitars now, the DR7 is always like running into an old friend - someone you can count on and someone who always has your back. The DR7 is great for beginners, great for pros, great instrument to create and be inspired on. Sometimes in life things come along for a little while that are special. The DR7 fits into that class.

I purchased a 1979 MIJ DR-7 a few years ago. It was in almost new shape, with a little finger wear on the fretboard, had no belly bulge, and sounded good with old strings as it was, but I took it to a skilled luthier and had a bone nut and saddle installed, neck stabilized (even though it was solid, he told me), and a setup. He told me that I had a nice guitar, and was impressed with it. I installed D'ddario 80/20 custom-light strings. Wow. It sounds as good as a lot of 60-70 era Martin D28's and D35's I have played, with a shimmering bright, well-balanced tone, and LOUD!. I use 11's so that I can hear myself sing. I have also played a few other Sigmas that did not sound close to this one. I guess age and care has a lot to do with final sound. If you can get a good one, have it inspected and set up by a competent luthier, and you will not be disappointed.

This is a 1970 SIGMA DR-7 made in Japan. Although it doesn't say that on the label. I assume it was made there. It is one of the first ever SIGMA MARTINS. Has a zero fret which is a great indication it was a 1st year model. The serial # is very Low. I have yet to see a lower one online. It has SOLID INDIAN ROSEWOOD BACK & SIDES. Solid Spruce Top. It sounds great like any other Vintage Martin from the late 60's early 70's. These guitars if you are lucky enough to find one compete with any Vintage Martin from that era. They were made right. The headstock inlay appears Brazilian. These DR-7 Rosewoods are quite possibly the best Sleepers around in the fake Vintage Guitar world. Where Dealers charge a fortune for Guitars of this quality.

Sigma DR-7

I just picked up a very early rare old Sigma DR-7 guitar. The serial number is 5560 On the label it doesn't even say MADE IN JAPAN. Though I'm sure it was. The Back and Sides are SOLID ROSEWOOD. It has the "ZERO" fret also making this one of the First ever made SIGMAS. It sounds just like an early 70's Martin D-28. A keeper for sure.

Is it for sale?
Sigma D-7

I bought this in 1979 new, and it's an OK guitar. I paid $199, and that's more than it's worth today. It certainly didn't compare to my solid sitka topped Yamahas that I bought for that price.

I have a 1977 Sigma DR 7S serial number 4214 which was hand made before they started making them with machines in 1979. Like to know the value.
DR-7

Hello. Do you by chance know the history of my Sigma? To the best of my knowledge, I bought it when I started my first job which would have been around 1977 or 78. I bought it new. It's a model 52S DR-7 and the serial number is 14974. Do you know what the original retail price was and is mine hand made? Also, what is the Martin equivalent of this model? D-18 or D-28? Thank you.
