Dean Markley Acoustic Guitar Phosphor Bronze XL, .010 - .048, 2062Astar rating 2Bill McCurdieOctober 11, 2009I've been using D'Addario phosphor bronze strings on my acoustic for 10+ years. Figured I'd try some other brands just for a change. The Dean Markley strings I put on don't stay in tune from day to day as opposed to the D'Addario strings which once set, vary little. The tension also seems a bit high compared to D'Addario strings.
