yea...i currently use martin marquis strings the extra light .010- 0.047 gauge...i want to get a heavier gauge and possible get a higher quality of string..got some suggestions...oh by the way if u didnt figure it out its for an acoustic guitar...and stop ask me what music i play beacuase i play what everyone else does
D'Addario EXP's. they sound awesome and last way longer than most other strings. I use the .012 - .053 gauge ones.
Just try all the major brands for yourself. Each brand of string can sound better/worse depending on your guitar. D'addario, Dean Markley, Elixir, Martin, DR, John Pearse, etc.
I love D'addario, but everyone has there own preference when it comes to strings. I'd advise you to try them all out, and decide for yourself.
