3 BAND PARAMETRIC EQ
This is a 3-band parametric equalizer allowing EQ for the
lower range, midrange, and upper range.
* Each press of [SELECT] takes you to the next available
selection for the band, in this order: Lo → Mid → High → Lo.
Parameter Value
On/Off Off, On
Low Q 0.5–16
Low Frequency 31 Hz–500 Hz
Low Gain -20 dB–+20 dB
Mid Q 0.5–16
Mid Frequency 164 Hz–2.6 kHz
Mid Gain -20 dB–+20 dB
High Q 0.5–16
High Frequency 1.0 kHz–16 kHz
High Gain -20 dB–+20 dB
Total Gain -20 dB–+20 dB
On/Off (Effect On/Off)
Switches the 3-band parametric EQ effect on and off.
* The following parameters affect the Lo, Mid, and High EQ
together.
Q
The range is narrowed as the value is increased.
This adjusts the equalizer bandwidth (the range of
frequencies to which the equalizer is applied). The
bandwidth is narrowed as the value is increased, resulting in
a more precise (“notched”) equalization. Use higher Q
settings to affect specific frequencies and give the tone
particular qualities. Conversely, the bandwidth becomes
broader as the value is lowered. Use lower Q settings when
you want to adjust the overall low end or high end and
change the overall tone.
Freq (Frequency)
Adjusts the ED’s center frequency (for the range affected).
The frequency (upper range) increases as the value is raised.
Gain
Adjusts the volume level for the equalizer adjusted with the
Q and FREQ settings above. The volume level for the
frequency range is boosted more as the knob is turned
further to the right of center; turning the knob to the left of
the center position cuts those frequencies.
Level
Adjusts the overall volume level of the 3-band equalizer. The
volume level is boosted more as the knob is turned further to
the right of center; turning the knob to the left of the center
position cuts those frequencies.
WAH
The wah effect creates a unique tone by changing the
frequency response of a filter.
With WAH, you can select the type to be used from the
following.
• Pedal Wah
• Touch Wah
• Auto Wah
Parameter Value

■ WH: Pedal Wah
The Expression pedal is used for real-time control of the wah
effect.
The GT-6B’s expression pedal automatically switches to the
wah pedal function when “WAH” is selected in FX Select.
