Chapter 4 The Effects Explained
Low Cut Filter
The low cut filter cuts the frequencies below the specified
frequency. This setting adjusts the frequency at which the
low cut filter will begin to take effect.
High Cut Filter
The high cut filter cuts the frequencies above the specified
frequency. This setting adjusts the frequency at which the
high cut filter will begin to take effect. When “Flat” is
selected, the high cut filter will have no effect.
Density
This adjusts the density of the reverb sound.
Effect Level
Adjusts the volume of the reverb sound.
WAH
The wah effect creates a unique tone by changing the
frequency response characteristics of a filter.
“Pedal wah” lets you use an Expression pedal or the like to
obtain real-time control of the wah effect.
“Auto wah” creates an automatic wah by cyclically changing
the filter, or by changing the filter in response to the volume
of the input.
“Fixed Wah” provides the effect obtained when a filter-type
effect is used with the wah pedal stopped at a given angle.
* When using an external expression pedal as a wah pedal, select
Fixed Wah (FW).
