Optima Acoustic Gold, .013 - .057, AG1747Mstar rating 5Martin FeagleMarch 9, 2011I put a set of Optima Gold plated lights on my Washburn D32SN on Nov.1,2010 and they still sound good. I put med on my Martin D35. I hope they last as long and sound as good in 4 months. I play Bluegrass Music, mostly Gospel and old country. I used Martin SP Med. strings prior to using these. They rate a full 5 stars
Optima Acoustic Gold, .013 - .057, AG1747Mstar rating 5Russell TJanuary 24, 2010I have tried just about every string out there on my Collings D2H Baaa dreadnought. Nothing drives it better than this string. It has the most natural full rich sound. These strings last longer than any string i have used,so i don't think they cost anymore and i change strings frequently. I am done searching this is by far the best string for me to play on any fine acoustic guitar.
