Sigma 00 R 28 VS open D swing

Big change : this one is in open D tuning (DADF, AD). Well actually CGCEGC, one step lower as usual, but that s the same. First time in 10 years I don t play in Drop G tuning. Open D is used in blues or celtic tunes. Not much in a jazzy mood, but obviously I can t do anything else. OK, then. Another first is the use of a Sigma double 0, the 00R28VS. Very nice guitar, repro of the Martin model, fairly priced.
