Active bass guitars have an onboard preamp that boosts the signal from the pickups. This gives them a brighter, more aggressive sound. Active bass guitars also need to be plugged in to a power source to work, and this usually means using a battery.
Passive bass guitars do not have an onboard preamp. This gives them a warmer, more mellow sound. Passive bass guitars do not need a battery to work, and they can be plugged into an amp without any additional power source.
If you are not sure whether your bass guitar has a battery, you can check the manufacturer’s website or contact the manufacturer directly. You can also look for a battery compartment on the bass guitar.
