During the last 5 years I have tried at least 10 different sets of strings on my M14 CP, Elixir, Pyramid, D'Addario, C.F.Martin, Ernie Ball, you name them.
With these strings I've finally found the perfect set. The bass is fat, but clear and warm, the mids are prominent, but not too loud, the trebbles are clear and strong, but not sharp.
This makes the whole setup sound perfect.
Restringing is much more comfortable in comparison to most strings, because the strings ends are wound with some kind of textile cord. Here's a big Thank You from my finger tips :-)
Funny enough, I don't like them that much on my Dreizehnter SJ15 which has an Adirondack top. For the cedar/mahogany M14 CP, however, they're perfect.
