Noise reduction
This applies a noise-reducing effect.
As with amps and effects, noise reduction must be set for each
program. If, while changing settings in the preset programs mode
or the user program mode, you switch to another program or to
manual mode or turn off the amp before saving the settings, the
changes that you made will be lost.
- 12 -
When the amp model is changed, the noise reduction setting is
returned to the standard setting for each amp.
Number of programs
Preset:
1. Hold down the TAP button to bypass the effects (the tuner function
is turned on).
2. Turn the VALUE 1 knob to adjust the sensitivity of noise reduction.
Turn the knob to the right to increase the noise-reducing effect. When
this knob is fully turned to the left, noise reduction is turned off.
Depending on your guitar, increasing the sensitivity of noise
reduction too much may cause interruptions in the sound.
