Passive vs active bass guitars: bass electronics explained | Guitar World

Passive bass and active bass are integrated? No need to be here, we will show you the difference

welcome! Have you ever been confused by all the electronic things covered by bass? As I can see, buy first 

It's tough enough even before you figure out the actual function of its electronics.   

Yes! After adjusting the controls, the former does not require batteries or magnification. on

-With jazz type bass, you will find a single tone control based on only two components. The first is the knob itself, which is also called pot in the abbreviation of the full name potentiometer. 

The second is the capacitor in the network. When the knob is turned counterclockwise, it will gradually reduce the treble frequency. This produces a sound that sounds heavier bass.   

Yes. Nevertheless, there are many changes, such as Fender's TBX tone control: it can control the bass and treble frequencies, but it is still passive. There are also systems that change the value of internal passive components in the audio circuit.   

Active circuits are battery powered, which means you can increase selected frequencies instead of just cutting them off. When active electronic devices are put into use, there are more options besides simple tone control.

Two common preamplifier circuits provide fixed EQ center and/or semiparametric equalization. Each one allows you to boost or cut two or three frequency ranges-treble and bass, or treble, midrange and bass.

Using the latter, not only can the center frequency be increased, but also the audio frequency spectrum can be scanned and specific frequencies can be selected.

Both can work with passive tone controls, or they can be replaced. What are all the other switches on the active bass? You may also find that there is a switch to select a different frequency center for the midrange.

In fact, there are other benefits to using active electronic devices than just shaping the sound. One advantage is that they can minimize the interaction between the pickup, the longer cable length and the amplifier input at the other end, all of which will affect your tone. Even on a fairly long cable length, a stronger signal without attenuation can be achieved to obtain a clearer and more powerful sound.

Many bass players want to be able to switch from active sound to passive sound, so some bass guitars provide preamp bypass options in the form of toggle or push switches.

Typically, active circuits use high-quality rectangular 9-volt batteries, although you will find that many instruments increase their power requirements by 18 times, in other words, two batteries. Higher voltage can improve the signal margin, which means how much signal the preamplifier can receive before distortion occurs. Your personal taste will determine whether this is right for you. Personally, unless I play a vintage instrument, I usually choose an 18V circuit.

Definitely many bass players want to be able to switch from active sound to passive sound, so some bass guitars provide preamp bypass options in the form of toggle or push switches.
