Introduction to Effects and Parameters
WAH
This effect creates a “wah” effect using the pedal controller.
Stepping down on the pedal creates a brighter sound, while releasing the pedal produces a
muffled sound.
When the wah effect is on, the pedal functions as a wah pedal.
When WAH is on: Functions as a wah pedal.
When WAH is off: Functions as a volume pedal.
NS (Noise Suppressor)
This effect suppresses noise and hum from the pickups.
THRESHOLD
This adjusts the effect in response to the level of noise. Increase the value when
there is a considerable amount of noise. Decrease the value when there isn’t that
much noise. A value of 0 switches off the noise suppressor.
* Setting the value higher than necessary may result in no output of sounds when the guitar
volume is low.
* Adjust this value until the decay of the guitar sound is as natural as possible.
MASTER LEVEL
This adjusts the level of the output from the ME-20.
* Raising the MASTER LEVEL knob too much may result in sound distortion.
* When the effects are all off, input and output are at the same levels as when the MASTER
LEVEL knob is at the center position.
* The setting of the MASTER LEVEL knob is stored in memory for each patch (p. 23).
