DR Strings Veritas Acoustic VTA-11

I bought these for a friend that owns a Godin A6 ultra and he was not satisfied with the guitar's sound and he would not use it that much. I was sure that the instrument is great and that smth else was the issue. I saw a video with a guy explaining the same issue and he said that with these strings the sound was great. Even though they are acoustic guitar strings, they work perfectly with the A6's humbucker as well. He had sound samples and I could hear the huge difference. My friend couldn't believe it when he placed these strings on! They say also that the strings last 4 times more than normal strings and it's totally true
