Chapter 4 Introduction to Effects and Parameters
Chapter
4
ACS (Advanced Compressor)
This is an effect that produces a long sustain by evening out
the volume level of the input signal. You can also use it as a
“limiter” to suppress only the sound peaks and prevent
distortion.
LM (Limiter)
The limiter attenuates loud input levels to prevent distortion.
TW (Touch Wah)
You can produce a wah effect with the filter changing in
response to the guitar level.
Parameter/
Range
Explanation
Type
see below
Selects the compressor type.
BOSS Comp
This models a BOSS CS-3.
Hi-BAND
This is a compressor that adds an even
stronger effect in the high end.
Light
This is a compressor with a light effect.
D-Comp
This models a MXR DynaComp.
ORANGE
This is modeled on the sound of the Dan
Armstrong ORANGE SQUEEZER.
Fat
When applied heavily, this compressor ef-
fect provides a fat tone with a boosted
midrange.
Mild
When applied heavily, this compressor ef-
fect produces a sweet tone with the high end
cut.
Stereo Comp
This selects a stereo compressor.
Sustain
0–100
Adjusts the range (time) over which low-
level signals are boosted. Larger values will
result in longer sustain.
Attack
0–100
Adjusts the strength of the picking attack.
Larger values will result in a sharper attack,
creating a more clearly defined sound.
Tone
-50–+50
Adjusts the tone.
Level
0–100
Adjusts the volume.
Parameter/
Range
Explanation
Type
see below
Selects the limiter type.
BOSS Limitr
This selects a stereo limiter.
Rack 160D
This models a dbx 160X.
Vtg Rack U
This models a UREI 1178.
Attack
0–100
Adjusts the strength of the picking attack
when the strings are played.
Higher values result in s sharper attack, creating a more clearly de-
fined sound.
Threshold
0–100
Adjust this as appropriate for the input sig-
nal from your guitar.
When the input signal level exceeds this threshold level, limiting will
be applied.
Ratio
1: 1–
∞
: 1
This selects the compression ratio used with
signals in excess of the threshold level.
Release
0–100
Adjusts the time from when the signal level
drops below the threshold until when limit-
ing is removed.
Level
0–100
Adjusts the volume.
Parameter/
Range
Explanation
Mode
LPF, BPF
Selects the wah mode.
LPF (Low Pass Filter)
This creates a wah effect over a wide frequency range.
BPF (Band Pass Filter)
This creates a wah effect in a narrow frequency range.
Polarity
Down, Up
Selects the direction in which the filter will
change in response to the input.
Up
The frequency of the filter will rise.
Down
The frequency of the filter will fall.
Sens
0–100
Adjusts the sensitivity at which the filter
will change in the direction determined by
the polarity setting.
Higher values will result in a stronger response. With a setting of
“0,” the strength of picking will have no effect.
