I have a Sigma DR-45 that has an ink stamp inside the body same as american made Martins. The stamp reads "Sigma Guitars Made in Japan for CF Martin & CO" next to that is also stamped " 2 DR-45" The guitar is Natural Solid Spruce top with Solid Rosewood back and sides. Has large abalone diamond shaped inlay at the 1st, 3rd, 5th, 7th, 9th, 12th, 15th, 17th frets. Abalone binding around spruce top, around the top and bottom of sides, around the back of body, and around the heel of neck, abalone rosette, around the fretboard where fretboard sets on top of the spruce top, abalone continues down on both sides of where the fretboard runs from top of body down to heel of neck, and down on the end block where strap button is from top of side to back of sides. It has the logo "Sigma Guitars est 1970" in a gold Mother Of Pearl inlay. The guitar was made between 1980-1984 from what I can find in researching on internet. The action is set so that a regular american quater(25 cent coin) just touches the low E as I slide onto the 12 wire fret. This guitar sounds just as quality as my 1990 Gibson J-45. I have performed what i call the S-G 45 sound challenge with a few long time Gibson acoustic owners/players and they honestly can't tell the difference. While they are standing approx 15 feet away with back turned to me with blind on I strum my Sigma DR-45 and my Gibson J-45 one at a time for about 20 full slow strums each and they can't tell the difference honestly without just guessing. I bought the Sigma DR-45 3 weeks ago at Guitar Center. Someone had traded it in and got a new Martin I was told when I spotted it hanging on their used acoustic section of the wall in the acoustic room. I got the employee to get it down for me as it was hanging from top rack. The strange thing is they had it listed as a 20DR on tag and price of $599. Well the lighting in the acoustic room is not all that great and I had to walk around to get a good spot for lighting and hold the guitar just at a weird angle to be able to get a good look at the model number and it is stamped " 2 DR- 45" I strummed it about 10 strums and then immediately grabbed an old old old used J-50 Gibson they had hanging there with a $3500 price tag(I have played this Gibson J-50 for last few months each time I stopped in there) and the Sigma sounded just as impressive, so I purchased the sigma for $599 as I never said anything to the Guitar Center about them having it listed as a 20DR. After I purchased it I looked at my receipt and my receipt says I purchased a Vintage Sigma 20DR for $599. The thing is I have not found any such Sigma model as a 20DR on the internet and can't find a 20DR even mentioned in the wiki history which is very detailed I may add. Also, the wiki history does mention the fact that sometime between 1989-1984 prior to Sigma moving from Japan to Korea they made several DR models including a DR-45. I have found that Sigma factory located in China is making and selling a new version/Copy of the Sigma DR-45 for $1000. The pic is not all that great they use on the website, but it appears to have the Abalone binding similar to my sigma, the China copy has a paper label inside on the Back panel that says Made in China. I can't find a Japan made DR-45 for sale anywhere on the internet so I can get an idea of what mine is worth. I would like to know if anyone has a clue as to what this Authentic Japan made Digma DR-45 would be worth. I will post some pics of it.
