I am a former professional rapairman and now a guitar builder of electric guitars. I have tried many many brand of strings, both acoustic and electric strings.
Read about these strings, and was qurious. I play mostly acoustic guitars in open tunings. The first I noticed was a bit reduced overall volume and lower 'energy' in the treble range. But after playing a while, I realized that the treble range was much more balanced than every other strings I have tried. Pleasing to the ears. Overall very good note separation and balanced sound. An eye opener to play strings that do not sound shrill with the treble range intact.
Although volume was a bit reduced compared to many strings, these string are the best I have tried for acoustic guitar. These strings will shine in recording situations and a very good choice for bright sounding guitars.
These strings should be standard on lower priced acoustic guitars due to that these guitars almost every time sound too shrill in the treble range.
As a bonus these strings have a lower string tension than normal strings. Very good strings, indeed.
