I restaured an old romantic guitar from around 1800.
I was afraid of tension to this old guitar, so i needed light tension, and preferable strings that mimic the sound of the old gut strings from that time. I decided to give these Aquilas a shot. The strings are VERY decent and have a warm tone.
Only cons are: the highest string (E or 1st) kept snapping when i got close to the tone (i tuned the guitar a half step lower). I decided to tune the guitar up from a B (si) by half a tone a day, which worked.
The strings remain stable in tune after 5-10 tuning sessions.
