Another string recommendation
. I just tried La Bella Vivace strings (carbon strings) on one of my guitars that needs some help with brightness and loudness in the treble strings.
These strings are the best carbon strings that I have tried so far. Bright and loud which is good for this guitar, but they also have this shimmering resonance that I have never heard before in treble strings. A somewhat metallic sound, but in a good way, a shimmering, almost echoing quality. Not sure if these strings will work well on a guitar that already has a good treble string response, but on this guitar they are great.
