Annoying resonance frequency removal - EQ technique

Post by hurghanico »

In a few cases cutting the extreme low and high frequencies (as described in my other article How to cut harshness and/or boominess from some cab/mic combos) could be not enough to fully smooth out the raw tone achieved with a certain combination of amp+cab+mic, since an isolated annoying resonance frequency could be located also in an intermediate point of the amp model frequency spectrum, ie not between the extreme low and high frequencies already covered before..

In this case you can use the Parametric EQ as a scalpel to find the annoying frequency, and then cut it to the point it's not too loud and annoying anymore..

To do this, first you need to narrow the Parametric EQ bandwidth, so set the "Q" parameter around 100%, and then turn up the Parametric EQ Gain around 100%, and then while playing one or more open strings on your guitar sweep the Parametric EQ Frequency..

As you sweep the Frequency, at one point the tone resonance will become extremely loud and unpleasant compared the other points.. and that's the point where you have to do your cutting, by lowering the Parametric Gain value below 50% (which is the neutral setting)..

Usually a Parametric Gain value around 40% should work nicely,.. with a Gain value less than 35% you would probably cut too much..

For a more natural and smooth cut the Parametric bandwidth Q works nicely when set around 85%..

In most cases you can find the annoying frequency into the 80- 90% range of the Parametric Frequency
