"Genius" NF-clear nylon, normal tension. A single crystal nylon wire for the high notes, and covered in silver copper with antioxidizing protection on the multiwire nylon for the low notes. The perfect string for concerts.
First of all Erwin(lord of the strings) is a 5 star dealer.
The Galli 65 are very musical and are superior in tone,balance and longevity to any string I've used to date.
They do take more time to settle in so patience is needed in tuning them for a week to 10days.
That's why I've given them only 4 stars though
I still highly recommend them.
"These strings are superb and a 'steal' at the price! Only just started using them and find them tonally superb: especially the basses. Personally, haven't found them any more 'fickle' at settling down on the guitar than any other string (at time of writing). These strings are definitely a 'must-have' from my point of view and would thoroughly recommend them. The strings wear well, are cheap to replace both of which lead me to play my guitar an awful lot more!!" GPM (UK)
maximum rating for these strings , good tonality and power for a low price
