Replace bass strings by loosening the old set, removing it, and threading the new strings through the bridge and onto the tuning posts. Match each string to its position by gauge, wind it onto its post, tune it up, and trim the excess. Work through the set and tune each string again after you stretch it.
Loosen the old strings
Turn the tuning peg for a string until the string goes slack, then unwind it from the post and lift it off the bridge. Work through the strings and set the old set aside. Loosen the strings before you remove them so the neck never takes a sudden change in tension.
Clean the fretboard with a soft dry cloth
With the strings off, wipe the fretboard and the body with a soft dry cloth to lift dust. Check the frets and the bridge for dust and wipe them too, and check the tuning posts for dust as well. A soft dry cloth is enough for this step.
Thread the new string through the bridge
Take a string from the new set and match it to the right position by its gauge, with the thickest string in the lowest position. Feed it through the bridge and pull it up to the tuning post. Check the gauge of the string before you thread it, since the gauges set the order of the set.
Wind the string onto the tuning post
Pass the end of the string through the hole in the tuning post, pull it snug, and turn the peg to wind the string onto the post. Keep the coils neat and close together as you wind, and keep tension on the string with your hand as you turn the peg.
Tune up and trim the excess
Bring the string up to pitch with a tuner, then pull it gently to stretch it and tune it again until it holds. Trim the loose end close to the post after the string holds its tune. Repeat these steps for the rest of the set, then tune the whole set again before you play.

Frequently asked questions
How do I know which string goes where?
Match each string to its position by gauge, with the thickest string in the lowest position and the thinnest in the highest. Check the gauge of each string before you thread it through the bridge.
How often should I change bass strings?
Change them when they look discolored or feel rough, when you see rust, or when they no longer hold tune. How much and where you play decides how soon those signs show.
Should I change all the bass strings at once?
Yes. Change the full set so the strings wear together and hold tune together. A single new string beside worn strings will feel different from the rest.
