C.F. Martin Acoustic Martin 92/8 Phosphor Bronze Extra Light, .010 - .047, M-530star rating 5Carlos CovarrubiasOctober 2, 2009These strings are excellent. They were everything I had imagined they would be. These strings made my old guitar smile and sing. The sound was wonderful. I also love the SP line of Bronze light .10 for 6-string acoustic. Carlos
