Learning How The Parametric Controls Works
Try this. Boost the level control in one section, so you will more easily hear the frequency you are
adjusting. Then rotate the frequency control directly above it. After you identify what frequency
you’re adjusting, return to the level control to adjust it to the desired amount of boost or cut.
Contour the sound to your liking. When you become experienced with parametric adjustment,
you can of course skip most of the above, but parametric EQ is a very powerful tool that is easy to
overuse. When it doubt, use less.
Fun With The Parametric
To determine the low frequency response of your speakers, add boost using the lowest frequency
parametric control. You’ll hear an increase in low frequency response. While playing the lowest
note on your bass, turn the frequency control down until the low frequency response disappears.
Turn it back up until you hear the boost again. Look at what frequency the control is set to. That’s
the low frequency response of your speaker cabinet.
Treble Control
This tone control is a shelving type, providing a 15 dB of boost or cut at slope starting at 2000 Hz,
which is above the fundamental notes of even a standard guitar. Frequencies below this are not
really affected, but frequencies above it are boosted uniformly. The control is detented at the 12
o’clock position for an easy and fast flat setting.
This may be a good place to discuss harmonics. It is the sound of natural and addition vibrations
that distinguishes one instrument from another. They are why a piano sounds different than a
guitar, for example, and are a primary reason you have a unique sound.
Harmonics can be defined as weaker vibrations that are higher than and mathematically coordi -
nated with the fundamental notes. Harmonics are caused by an infinite variety of factors, includ -
ing for example where and how you pluck a string, the type of string, the wood the bass is made
from, the response of the amplifier, speakers, etc.
Timbre Control
This unique control is great for making rapid and useful adjustments to the overall tone. One use
is to compensate for different instruments, for example changing a Rickenbacker to a “P” bass.
Another use is to make a quick mid-set change from a Funk to a Reggae song.
