I'm a big fan of Martin strings, and I love the way they feel. The 80/20s work great for fingerstyle--they give nice chime and clarity. Very articulate, and they sound nicely balanced on my Lowden. The only problem is that they die out a bit quick, in less than a month for me.
Good thing Shoreline offers them for such a great price!
I have used Martin SP 3100 strings on all of my guitars. Not only my Martins but I have several other makes as well. I am retired and only change my strings about every couple months now. But I am very glade I found Shoreline Music because they have an excellent price on the strings I use. Thank you Shoreline and keep up the good wood.
