C.F. Martin Acoustic Guitar Six String Phosphor Bronze Medium Extended Life, .013 - .056, MSP-PLUS-4200star rating 5Mike TwiggNovember 23, 2009I am quite pleased with these strings. I am still a big fan of Elixirs BUT these strings have a sound that makes my MARTIN really sound like a MARTIN!!
C.F. Martin Acoustic Guitar Six String Phosphor Bronze Medium Extended Life, .013 - .056, MSP-PLUS-4200star rating 3Gene HoldwayNovember 17, 2009Excellent tone, but nowhere near the wearability of the Elixir nano phosphor. The value would be good if you are not playing at lot at $9.00 per set. Performing musicians will want more life from the set. I play pretty hard, but expect longer wear.
