I change my strings on a regular basis because on average I perform 2-3 times per week. I have used many types of strings in the past for my martin OM acoustic. However these light gauge strings are great and originally bought them because i needed some light strings as my fingers were sore due to playing 3 nights on the run. However I really like them, nice & warm, great sound, great for rhythm playing and solos! I would recommend these, and so far they've lasted well without any string fade, or change in sound.
