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

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denedasweakervibrationsthatarehigherthanandmathematicallycoordi-
natedwiththefundamentalnotes.Harmonicsarecausedbyaninnite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amplier,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.
