Chapter 9
AC (Acoustic Guitar)
Setting the parameter of acoustic guitar.
STEEL
Parameter/
Range
Explanation
MIX LEVEL
COSM GUITAR
0–100
Specifies the level of the COSM GUITAR.
NORMAL PU (Normal Pickup)
0–100
Adjusts the volume of the normal pickup.
Parameter/
Range
Explanation
NS (Noise Suppressor)
This effect reduces the noise and hum picked up by guitar pickups.
Since it suppresses the noise in synchronization with the envelope of
the guitar sound (the way in which the guitar sound decays over
time), it has very little effect on the guitar sound, and does not harm
the natural character of the sound.
SW (Noise Suppressor Switch)
OFF, ON
Turns the NS effect on/off.
THRSH (Threshold)
0–100
Adjust this parameter as appropriate for the
volume of the noise. If the noise level is
high, a higher setting is appropriate. If the
noise level is low, a lower setting is appro-
priate. Adjust this value until the decay of
the guitar sound is as natural as possible.
REL (Release)
0–100
Adjusts the amount of time from the point at
which application of the noise suppressor
begins to when the volume is fully attenuat-
ed.
Parameter/
Range
Explanation
BODY TYPE
Selects the type of resonating body.
MA28
The sound of a Martin D-28.
Older model known for its exquisitely bal-
anced sound.
TRP-0
The sound of a Martin 000-28.
This model features a full low-end reso-
nance and crisp, distinct contour.
GB45

This vintage model features a unique, sea-
soned tone with good response.
GB SML
The sound of a Gibson B-25.
Featuring a compact body, this vintage
model is often used in blues.
GLD 40
The sound of a GUILD D-40.
This model features warm resonance from the
body along with a delicate string resonance.
BODY
0–100
Adjusts the body resonation. Raising the val-
ue produces more of a sense of the guitar
body in the sound. Lower the value in condi-
tions where feedback is prone to occur.
TONE
-50–+50
Adjusts the tone of the body. The standard
value is 0; raising the value boosts the high
range.
LEVEL
0–100
Adjusts the volume of the body. With a set-
ting of 0, there will be no sound.
