EQ
The 4 Band Semi-Parametric EQ lets you emphasize and de-emphasize selected ranges of audio
frequencies, from bass to midrange to treble. The knobs on the left of the EQ’s control panel let you
choose the frequency that each of the 4 bands of the EQ will focus on, and set the amount of gain that
will be added to or subtracted from that frequency band.
The top knob pair is for the highest frequency range (the treble), providing a high shelf which boosts
all the audio at and above the frequency point you select. As you make changes to this and the other
EQ bands, the resulting EQ curve is shown in the EQ control panel’s display area. The second knob
pair down controls a bandpass filter for the for the high-mids, boosting frequencies at and around the
frequency that you select. The third knob pair down is for the low mids, and the bottom knob pair,
for the bass, controls a low which boosts all the audio at and below the frequency you select. Press the
RESET button to “zero” out all the gains, and set each band to a default frequency point, which is
generally a good starting point when you want to make EQ adjustments. As you make EQ adjustments,
it’s a good idea to frequently check what the Tone sounds like with the EQ turned off, to make sure
that you’re really making improvements when adding EQ!
Gate
The Gate is designed to reduce the noise that your guitar or other source makes when you are not
playing. You can think of it as a gate that opens to let your guitar or other sound through when you
play, and closes when you stop playing to shut out the noise you would otherwise hear after you stop
playing. (For guitars and basses, the Hum Reducer is available to tame noise in another way.)
The Gate works by detecting the input level coming into GearBox. When the input level is below
the level set for the gate’s THRESHOLD knob, the gate will close at the speed set by the Gate’s
DECAY knob, and cut off the signal from your input. When the input level is above the threshold,
the gate will open to let your input signal through. Turning the Threshold knob clockwise increases
the aggressiveness of the gate in its effort to cut off sound. The idea is to set the threshold low enough
so that it doesn’t cut off the signal as you are playing or a note is sustaining, but high enough so that
the background noise from your guitar or other source doesn’t keep the gate open. When you’re using
a Stomp effect, Amp Model or Preamp Model that adds a lot of distortion to your Tone, you’ll need
to adjust the Gate to work well with that, and you’ll probably have to tweak the Gate if you change
Models, change drive settings, or use different guitar(s), pickup configurations, or other changes to
your input source, and the volume of audio that it’s providing.
You can turn the Gate on/off by clicking its icon, and the setting of the Gate is saved as part of a
Tone.

Vol (Volume)
The Vol (Volume) allows a MIDI controller to operate a volume pedal effect in GearBox to control
the volume of your processed sound. The CONFIGURE switch on the Volume control panel lets you
decide whether the volume pedal will run before the amp/cab/mic or Preamp processing (“Pre”), or
after (“Post”).
Female De-Esser
The Female De-esser should be your first choice when taming the Sss and Shh sounds of female
vocalists, although as with all things musical, you may find many uses for it and may find that for some
male vocalists it works better than the Male De-Esser. For general information on De-Essers, see the
Set the De-Esser topic in the How To section. Technically-savvy users will want to know that this de-
