60-125 

A set of strings for a 4-string electric bass with a drawbar of 60-125 is a set of four strings designed to be used on a standard four-string electric bass.

The "draw" refers to the thickness of each string and is measured in thousandths of an inch. In this case, the draw is 60-125, which means that the thinnest string (the first string) is .060 inches thick and the thickest string (the fourth string) is .125 inches thick.

Electric bass strings are usually made of stainless steel, nickel or alloy. Thicker bass strings produce deeper, lower tones, while thinner strings produce higher, clearer tones. The choice of string will depend on the bassist's playing style, sound preferences and playing technique.

In summary, a set of strings for a 4-string electric bass with a drawbar of 60-125 is a set of four strings of different thicknesses designed to be used on a standard 4-string electric bass to produce a range of low and high tones.
