SOL ° G ° 3

This is a guitar string for a classical guitar with a standard drawbar. The letters "G", "G" and "C" refer to the three lowest strings of the guitar (from lowest to highest), which are tuned in G, B, and C respectively. The "°" symbol means that this is a spun string, which means that it is made of a nylon core with a metal wire wrapped around it to provide better strength and a richer sound.

The "G ° 3" indicates the thickness of the string. The number 3 represents the string number, which corresponds to the G string, and the symbol "°" indicates that it is a spun string. The "G" indicates the note of the string, which is a G. The "°" symbol is often used to indicate a spun string, but it can also indicate an unspun nylon or carbon string.

The draw of a guitar string refers to the thickness of the string, measured in millimeters or inches. A higher draw means a thicker string and higher tension, which can provide a louder, more powerful sound but may be more difficult for some guitarists to play. The standard drawbar for a classical guitar is generally considered a medium drawbar, and there are lighter and heavier drawbars available for those who prefer a different sound or feel.
