An acoustic bass string is an essential part of the instrument that produces the sound when you play. Strings are made of metal (usually phosphor bronze, stainless steel or nickel alloy) and are available in different thicknesses, or diameters.

The string diameter measurement is given in millimeters or inches, and is usually the size of the thinnest string in the string set. For example, an acoustic bass string sold as a .045 draw means that the string has a diameter of .045 inches or about 1.14 mm.

The term "draw" refers to the tension of the string. Acoustic bass strings are graded according to their tension, ranging from light to heavy. The higher the tension of the string, the greater the force required to pluck it, but the brighter the sound and the stronger the projection.

In summary, a single .045 string is a single string with a diameter of .045 inch, which has a medium tension and can be used to replace a broken or worn string on your acoustic bass.
