La Bella 7SG Classical 7-String

These strings sound pretty good, but for special performances I would use different combinations of single strings.

For the price, you get a pack of strings that sound alright! I use these for study and for low-stress performance at Brazilian/Latin jam sessions.

As with all strings, the instrument is a big factor in the sound.
I've used these strings on two guitars: a beautiful hand-made classical, and a mid-price instrument by Ibanez.
On both instruments the strings have a good (not bad, not great) response to different timbres.

In conclusion, these are mid-priced strings good for studying. If you need a particular sound, you have to put together your own custom combination of treble and bass strings.
