You need to be familiar with your musical instrument. We’ve briefly described the bass guitar with the aid of a picture and little description below the image.

The tuning machines are used to tune the bass guitar so that they would sound correctly.
You should know by now that without the strings of the bass guitar there is no bass guitar. This is because you won’t have anything to strike as a player.
The strap pin and end pin are used to hook the strap on(or belt) so you can hang the guitar on yourself.
The controls are used to adjust the sound settings to suit yourself.
