I put these on my Amalio Burguet (Studio Series) and the tone quality was wonderful. However, the trebles were very hard so I have to replaced by the softer strings.
Pros: Very good string, the basses make powerful sound, and the trebles sing warmly.
Its golden-colored strings look fantastic particularly on the spruce guitar with an ebony fretboard.
Cons:
The string tensions are high (not medium-high). Its string tensions (lbs.) are 17.64, 14.99, 14.99, 17.64, 17.20, 16.53.
Please compare the tensions with that of D'Addario EJ46 Pro Arte Hard (16.810,12.420,12.300, 16.240, 16.960, 15.210).
In particular, the tension of the trebles feels. Given this, I do not recommend these strings for beginners/intermediate guitarists as well as people who prefer the soft strings.
The Price is high (but still it worths).
