Or if you want coated strings, the D'Addario EXP-14's are the same 12-56. Light top, medium bottom. They sound really nice on my new Breedlove. It's a concert size but I'm gonna try these on ALL the guitars just to see. And they last longer!! The Earthwood 80/20 Lights (11 - 52) that I tried on the D65 were initially bright and okay until they broke in and now they're just too quiet for me. I need a little more volume. I have 4 more different types of strings to try. Just keep playing and throwing strings on there. If they're too heavy for you use lighter. If they're too light use heavier. If you can't decide use another kind. Your guitar is always gonna need new strings.......
Ah, Tom the Earthwoods were my recommendation, right? Sorry they didn't work for you. I change my strings every month, so just about when they get bit "worn", I'm changing them anyway. I love their brightness, and I love playing new strings...
Anyway, griehund, so many strings to choose from, not enough hours in the day to try them all. It looks like your quest is just beginning...
