[Rwp] How does eq works - cutting frequencies off guitar amp tracks.

[Chris Belle]

Hadi?
Enjoyed working with you  and good to see you here
Eq is most definitely available in reaper in many forms.
The js plugs offer simple tilt eq, different flavors of graphical eq and 
parametric, and the cockos stuff
has a nice parametric and multi-band.
Graphic equalizers
have set bands, while parametric eq
can be variable, you can change the frequency of the bands
as well as change how wide and narrow they are.
Shelves are like a slide, with variable steepness while high and low 
pass are like hard limiters, let's nothing through above and below a 
certain point.
One can certainly train their ear to  hear
certain frequencies, and to home in on problem areas, or for creative 
tricks.
YOu know a wa wa pedal on a guitar is nothing more than a notched eq 
being swept up and down in rhythm there's lot of info out here and I'm 
happy to work with you with this stuff but here are some very broad 
guidelines.
Your kick drum thump hit in the chest lives around 60 to 80 hertz.
Bass guitar around 120 hertz,
but the higher end punch of a bass can go all the way up to 2.5k,
the low warmth of a vocal is around 250 hertz,
vocal clarity is 2k to 4k range, the sibbalance of the s sounds
at in the 6 to 8 k range, and drum cymbals are in the 10 to 16 k and 
that's also where your air and shimmer are.
Your telephone kind of honkey sound is 1.5 to 2 k,
these are very general guide lines, and when dealing with complex 
harmonics, everything afects everything else, so it's not like it's all 
isolated.
For instance, the kick drum may thump at 60 to 80 hertz but the tick 
part of the beater head is in the 2 to 4k range,
or even higher, and you can creatively make your beater sound sharp and 
punchy or more broad and pillowy.
you can put warmth on a snare by boosting 250, or make it sharper by 
ramping up 4k.
5 to 7 k on guitars can be desirable for a bright rhythm funk track, but 
maybe anoying for metal with distortion.
when you want a more warmer over drive tone.
So bring up reaeq
and play with your bands, you can't hurt anything, seee what happens 
when you boost and cut certain frequencies,
make a narrow notch with reaper, the higher the q number the broader the 
bell, the smaller the number the narrower the bell, and make a narrow q 
and practice sweeping the frequency up and down with boost or cut and 
see how it sounds, when you hit a spot with lots of energy in a certain 
band, you'll know it because it'll really be exaggerated.
Eq can be used for sound sculpting for tasteful tone tweaking, or for 
surgical removal
of unwanted energy.
At the heart of things ,\
it's just a fancy volume control, but for different parts of the spectrum.
high  pass filters and low pass filters can be used in very interesting 
ways for resonant peaks,
a high pass filter with a steep q will actualy
enhance the frequencies around the  setting, and make them jump out.
All in how steep you set the q.
And on and on it goes.
