Default How to deal with boomy notes which cause clipping in amp?

So my G note gets pretty boomy because of the guitar's main air resonance.
I noticed that while playing outside today, that note can spike up the volume/frequency which then causes clipping in my amp.

I was wondering if any of you are familiar with this issue?
Is there a way to control the offending note's frequency,
So that it doesnt stand out and clip my signal?

Which G? On the bass string? Is it just G, or is it any note played on that particular string. With an under saddle pickup, commonly the low E and/or high e strings are out of balance due to there being more downforce on the saddle and consequently on the pickup at the ends.

Let's first find out why, then we can work on the how.

To answer your question, some EQs are capable of "pulling out" a note out of the signal, so it can be done.

I suspect your pickup is not evenly balanced across the strings...

You need a Parametric EQ to tame it. Add a sharp cut at 100 Hz.

The open G is quite boomy,
But also the G note on the 4th (D) string on the (5th fret).

The boominess is there also when I am unplugged.
It's just a guitar resonance thing I guess, which gets amplified when amplified hehe

That's what soundhole plugs are designed for.



There may be other issues and valuable solutions which others have described in your situation but if chamber resonance is the main one then a decent f/bb will get you most of the way there.

G2 and G3 are at 98hz and 196hz, respectively. So an eq with 100 and 200hz settings could possibly help to cut those frequencies out. The LR Baggs PADI has a notch filter that can be dialed in for particular notes as well.

Good luck with it.

Reducing the sound hole area will lower the chamber resonance frequency. I'm surprised it isn't lower than G (98Hz) with the sound hole completely covered.

Ok, need more info:

Guitar (type/model)
Pickup (type/model)
Preamp/EQ
Amp model
Typical performance environmemt
Existing tools available (EQ pedals, cement mixer, etc.)

Agree with YamahaGuy, a notch filter will work.

Oh, that's because I have a small soundport on the upper side !
I should try and cover that too,
however I am afraid it will kill the tone.

Sometimes at homes, sometimes on the street busking.
Got a small 7EQ pedal - Ammoon 3C where the 1k frequency is lowered drastically because it just sounds like **** lol

How close is the amp placed near you and is it in front of you, to the side, or behind? Set fairly high in volume?
Have you tried some distance between you and the amp?
