Single Bass Strings
Single strings are incredibly handy in the event of a string breaking from a relatively new set, or if there's any other issue with one of the strings in the set. In such instances, you can avoid the expense of buying an entire new set by simply purchasing a single string. When selecting your single strings, ensure they are of the same type and gauge as the strings you are replacing.
For a deeper understanding of concepts related to type and gauge, consult the info box in the 4-string bass set section.
