I have been experimenting with different strings on my acoustic guitar for a couple months and I really like martin strings. They feel great and are smooth on my fingers and have a very warm tone, but also have a nice brightness that is not overpowering. These strings give my acoustic guitar a growling bass with crisp highs and an awesome tone. After a couple weeks of continuous playing they still have their new string tone and you can’t see any dirt or grime build up. It’s easy to say that I have found my strings and will no longer try anything different.
