Just bought some new strings for my Martin Shenandoah 12 string. First, I was surprised to find that Martin no longer makes this guitar. The owner of the music store told me he wished Martin still made them - he could sell a lot of them. I've had it for about 15 years and it is a fine sounding instrument. Second, when I got home from the music shop, I found that the strings I had bought were Martin Marquis extra lights (Obviously I didn't look at them close enough). Since I had always used light strings, I called the owner and told him I had the wrong strings. He said I could bring them back if I didn't like them, but that everyone he knows who plays a 12 string is using them now. I have always tuned down a half step, but since these are extra light strings, I decided to use concert tuning. The action is good and the sound is not bad. Maybe I could get used to it, but I think the lights sound better. Any opinions are appreciated.
