Assalamualaikum .

Some terms wee need to know before we get in to this :

► Audio Level unit : db

► Frequency Unit : hz

► Human hearing Range : 20-20000hz (max)

► EQ band : Adjusting a Choosen frequency Range


  •  What is EQ? What Does it do? What does it even mean? What Does it look like!? 


EQ Stands for Equalizer .  It is a tool for shaping tone/frequncy response of an audio source . ( This is the tool for making your guitars sound “mota” “chikon” “Metallica” 😛 )

There are two types of EQ :

  1. Graphic Equalizer
  2. Parametric Equalizer


Graphic EQ :


This what a Typical Graphic EQ looks like. It has bands with Fixed frequency Range.

It means, The faders will only affect the frequency range that is fixed for the particular fader / Written on the unit . Say , The 3rd fader or band , if you count from left,


Will only affect the frequencies around 400 hz and mostly 400 .  same applies for each faders .  and the DB metering will give you an idea of how much you are adding or taking out.


So isn’t this all? isn’t this what an eq is supposed to do?

Yes, There are not too many Differences Between the parametric and Graphic Eq , Except for, The Parametric Eq Gives You more control and options



This is what a Parametric EQ looks like…

Ermm.. Too much knobs!

well actually lets look at a simpler one


(what the heck? is this what you call simple? -_- )

So this is what A typical Parametric EQ Looks like . Well still Too much knobs…I know.. I know..

they are Pretty Simple , ( !! -_-  )


SO , A parametric EQ has several Control knobs for each band

Frequency Knob selects the region where you want to boost, or attenuate/take out .

Q/Bandwidth knob controls the area/size of the region you wan to work with the specific band

Gain knob determines how much of that frequency region you want to add in or take out.

Still not clear right?

Okay , So Lets go back to graphical Eq for a sec.

say you want to add Mids .  so You will go for the faders in the middle of you graphic EQ , in This case 800hz  and the 1.6khz Fader and increase the gain or push the faders up.

You like the sound , but that 1.6khz fader is adding a little bit of upper mids or something like that you dont like. so You will basically decrease the gain on the 1.6 khz . but , naaahhh it doesnt sound as expected.

So this where parametric eq would come in.First  you will have find where that freq is available .

As you can see, Both in HMF section and LMF section , the 1.6khz is available. Any of them will do . So lets take the LMF one.



now what you will do is, Set your Freq knob around 1.6 kz  and you will boost it , or add in , with the Gain knob . now,  You like the sound , but that upper mids you dont want is still there.

So there are a few ways to solve it .

1.You can simply change the frequency by adjusting the frequency knob . set it to something around 1.2khz or 1.4khz , this should work, or alternatively,

2.you Can Decrease the Bandwidth , keeping the freq knob at 1.6khz or moving it a little to the left (1.4/1.3) with the Q/bandwidth decreased a little bit .


There’s another way of solving this which I will show you when I write an article on How to EQ Guitars.

Parametric EQ’s are mostly for mixing guys or “nerds” actually, It is used to kind of do the final touch ups.  So You wont need it much for dialing in a guitar tone as this is mostly used as a post processing tool .

If you are a just starting out , This might seem a bit confusing Which is totally Fine.

I will now be explaining everything in Bangla In the video below.
