20 Guitar Multi

Comp (Compressor/Sustainer)

This effect compresses the level of the signal by
reducing the level of strong input signals and
boosting low-level signals.
1. Output Level
Value: 0–100
This adjusts the Compressor volume level.
2. Tone
Value: 0–100
This adjusts the compressor tone.
3. Attack
Value: 0–100
This adjusts the attack strength when the sound is
input.
4. Sustain
Value: 0–100
This adjusts the length of time that the compressor
continues to raise and hold the level of weak input.

Wah (Auto Wah)

Wah is an effect created by the periodic change in a
filter's frequency characteristics, giving a particular
kind of tone change. You can get the wah effect by
changing the volume of the input sound or by using
cyclical time-based changes.
1. Filter Type
Value: LPF, BPF
This selects the type of filter used to make the wah.
This selects either the BPF (band pass filter) or LPF
(low pass filter).
When set to BPF, the wah effect occurs within a
narrow frequency range; setting this to LPF produces
the wah effect over a wide range of frequencies.
2. Trigger Sens
Value: 0–100
Sets the sensitivity level when wah is added through
changes in the source sound volume. The wah effect
is added at lower volumes as the volume increases.
3. Peak
Value: 0–100
This sets the amount of wah effect near the reference
frequency. The range narrows as the value increases;
lower the value to get the wah effect over a wider
range.
4. Freq
Value: 0–100
This sets the reference frequency for the wah effect
(the frequency at which the wah starts).
5. Polarity
Value: DOWN, UP
When the wah effect is added through changes in the
source sound volume, this setting is for selecting
whether the effect is to be added to the high
frequencies (UP) or lower frequencies (DOWN).
