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 bass
volume is low.
* Adjust this value until the decay of the bass sound is as natural as possible.

MASTER LEVEL

This adjusts the level of the output from the ME-20B.
* 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).
