XT (65-85-110-135) 4-string bass set, 135 with exposed core
A 4-string electric bass string set with a 45-135 gauge refers to a set of four metal strings designed to be mounted on a standard four-string electric bass.
The numbers 45-135 refer to the thickness of each individual string, measured in thousandths of an inch. The first string is the thinnest and measures 0.045 inches (about 1.14 mm), while the fourth string is the thickest and measures 0.135 inches (about 3.43 mm).
The choice of a specific set of strings depends on the desired sound, playing style, musical genre and personal preference of the bassist. Thicker sets of strings may have a more powerful and richer sound, while thinner sets of strings may be easier to play and more suitable for faster playing styles.
In general, thicker strings tend to produce a thicker, richer sound, while thinner strings tend to be brighter and clearer. However, the choice of strings will also depend on the configuration of the instrument, the string pitch, the type of pickups and other factors that influence the final sound.
