Correct. My issue isn’t with dialing in fx parameters per se. Its more about needing to learn how to deep edit eq. I really need to learn what a parametric eq is all about.
The hi/lo shelf, hi/lo pass, peaking, gain only options are what I really don’t understand.
As of now I’ve just been copying what Leon Todd is doing with his gear. It’s working very well but I’m still not understanding the deeper workings.
It’s like learning to copy someone’s guitar solo but still not understanding the theory behind the note choices.
They are like the EQ knobs on your amp, except you know exactly what they are doing.
B M T are like a 3 band eq. Resonance and Presence make it 5 bands of eq.
Resonance is low frequencies < 120 Hz.
Presence is high frequencies > 8KHz.
Bass is probably centered around 400Hz.
Mid is centered somewhere around 1- 3KHz.
Treble is in the 2-5KHz region.
The center frequencies of amplifier EQ bands will vary by design. Its what makes amps sound different.
A 10-band eq pedal is twice as many adjustment points.
You could keep all your amp controls at "5" and adjust everything with a 10 band EQ pedal in the loop.
People use 10-band eq pedals to give them more accurate control of frequencies.
Parametric EQ is an eq band that is not fixed. It can be "swept" to whatever frequency you want.
The "Q" control is how wide the parametric band is. A narrower band is more surgical and will have a noticable effect. A wider Q covers more space in the frequency.
A shelving EQ will adjust the frequencies above or below a certain point. Low pass filters (LPF) and high pass filters (HPF) are shelving controls. A LPF cuts off high frequencies. A HPF cuts off low freqencies. Sometimes shelving EQ allow you to adjust the slope.
Typical amp EQ controls can be simulated using a parametric EQ. You just have to set the center frequencies and Q correctly.
When you start custom crafting eq using GEQ and PEQ, there is a good chance you wont sound as good live. Real amps are tested to sound good on stage. Tweaking the eq curve when playing direct is what a music producer does in the studio to get everything to sound good in the mix. Solo channels often have mids boosted to stand out.
That is about all there is to it.
