Acoustic Fingerstyle Guitar Strings. Nickel Bronze Wound. Evolutionary synthesis of acoustic guitar strings. The double winding Nickel & Bronze strings combine the brilliant and defined sound of electric guitar Nickel strings and the warmth and depth of acoustic Bronze strings. The result: a more balanced sound and INFINITE sustain. The properties of the Nickel allow the vibrations to be detected in the best possible way by all the pickups, in particular by magnetic ones (for both acoustic and electric), without losing the tone of the bronze strings. The two thin windings make the string less "rough" to the touch and as a result there is less rubbing noise and an increased string life without the use of coatings that could reduce the vibrations (less space between "round windings" therefore less dead skin and sweat deposit). The only limit is your imagination! Play Galli. Everywhere.
