Last but certainly not least is the bridge. This is where the strings end at the bottom of the bass guitar. Most bridges consist of a metal base with several components attached to it.
The bridge base is screwed directly on the wood of the body. At the bottom are holes where each string is strung through. Some bass guitars have holes going down through the body for the strings, but on most the strings only go through the bridge.
The strings each pass over a movable metal piece called a saddle. Each saddle has a groove in the middle for its string. It is connected to the bridge base with screws that can be used to adjust its position and height. These adjustments aren't something you should worry about if you're a beginner.
