Had been using the OEM recommended D'addario EXP16 strings on my Wechter TO-8442 12-fret Triple-0 guitar but was uncomfortable with their squeeky feel and angular, crystalline sound. These 610LM's eliminated both issues, and provided better balance to boot! With these strings on, I sincerely believe my guitar sounds as good as any small-body Martin in the shop. they play more easily than the EXP16s, and feel somehow easier on the fingertips of both hands. Thanks John Pearse!
