7) NR (Noise reduction)
Use the Value dial to adjust the depth of the
noise reduction.
Adjust the
depth of noise
reduction
Increasing this value will produce more noise
reduction. Normally you will adjust this so that
you do not hear obtrusive noise when the strings
are lightly muted.
If the NR value is raised excessively, the sound
may be cut off prematurely. If this occurs, re-
duce the value.
Adjust the NR level as suitable for your guitar,
or pickup.
8) NOTCH (Notch effect)
This effect is a notch filter that minimizes acous-
tic feedback. Use the value dial to select the
notch point at which the acoustic feedback is
least. The notch point will move toward a higher
frequency as you turn the value knob toward
the right.
