RING MOD (Ring Modulator)
This creates a bell-like sound by ring-modulating the guitar sound
with the signal from the internal oscillator. The sound can be
unmusical and lack distinctive pitches.
ANTI FB (Anti-feedback)
This prevents the acoustic feedback that can be produced by the
body resonances of a guitar.
ADV.COMP (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.
Parameter/
Range Explanation
MODE
This selects the mode for the ring modulator.
NORMAL This is a normal ring modulator.
INTELLIGENT By ring-modulating the input signal, a bell
like sound is created. The intelligent ring
modulator changes the oscillation frequen-
cy according to the pitch of the input sound
and therefore produces a sound with the
sense of pitch, which is quite different from
Normal. This effect does not give a satisfac-
tory result if the pitch of the guitar sound is
not correctly detected. So, you must use sin-
gle notes, not chords.
FREQ (Frequency)
0–100 Adjusts the frequency of the internal oscilla-
tor.
EFFECT LEVEL
0–100 Adjusts the volume of the effect sound.
DIRECT LEVEL
0–100 Adjusts the volume of the direct sound.
Parameter/
Range Explanation
FREQ1–3 (Frequency 1–3)
0–100 Set the fixed frequency point at which feed-
back will be cancelled.
You can set up to three cancellation points.
DEPTH1–3
0–100 Adjusts the degree of the anti-feedback at
each of the three cancellation points.
Parameter/
Range Explanation
TYPE
Selects the compressor type.
BOSS COMP This models a BOSS CS-3.
HIBAND 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.
