I own a Sigma DR-11 that is appointed exactly as described in Dave B.'s post of July 15th, 2006; J. Kaufman's post dated June 16th, 2005 and Sterling Webb's post of November 3rd, 2004 where he states that he had heard the DR-11 was the rarest Sigma model.

Adam St. James, who is or was the editor of Guitar.com, owns a Sigma DR-11 as well. In a product review for the Fishman Aura that Adam wrote for Guitar.com, he describes the Sigma DR-11 as a "beautifully appointed, lower-priced version" of Martin's D-45. Mine looks exactly like a D-45 with the exception of the 3 piece rosewood back and bracing. If anyone knows how to contact Adam, he may be able to shed some light on the value and rarity of this guitar. My emails to him have kicked back as undeliverable.

This thread is the only place I have ever found in the twenty five years I have owned my DR-11 where it has ever been mentioned. I have had numerous Martin dealers tell me that the model number never existed.

I am very interested in establishing a value range for the DR-11 in mint condition with an original hardshell factory case.

Does anyone have any idea other than the original cost in 1980 of around $400?

Please advise,
