OVERTONE

This effect uses MDP (Multi-Dimensional Processing) technology
to add new harmonics to the sound, producing resonance and
richness that was not present in the original sound.
Parameter Value Explanation
LOWER Adjusts the volume of the harmonic one octave
0–100
(LOWER LEVEL) below.
UPPER
Adjusts the volume of the harmonic one octave
0–100
(UPPER LEVEL) above.
D.LEVEL
0–100 Adjusts the volume of the direct sound.
(DIRECT LEVEL)
Adjusts the amount of the detune effect that
DETUNE

adds depth to the sound.
TONE -50–+50 Adjusts the tone.

FEEDBACKER

Generates feedback performance.

AC. PROCESSOR

This processor allows you to change the sound produced by the
pickup on an acoustic electric guitar, creating a richer sound
similar to that obtained with a microphone placed close to the
guitar.

Explanation
Adjusts the time from when the direct sound
is heard until the harmonist sounds are heard.
Normally you can leave this set at 0 ms.
* When set to BPM, the value of each
parameter will be set according to the
value of the "MASTER BPM" specified for
each patch. This makes it easier to achieve
effect sound settings that match the
tempo of the song.
* If, due to the tempo, the time is longer than
the range of allowable settings, it is then
synchronized to a period either 1/2 or 1/4
of that time.
Adjusts the feedback amount of the harmony
sound.
Adjusts the volume of the harmony sound.
Adjusts the volume of the direct sound.
Explanation
If TRIGGER is ON, a feedback effect is applied.
This can be assigned to the [CTL1] pedal etc.,
and operated.
(Refer to"ASSIGN 1–6" (p. 17)).
Adjusts the ease with which feedback will
occur when the FEEDBACKER is on.
Explanation
This is the sound of a small-bodied acoustic
guitar.
This is a standard, unadorned acoustic guitar
sound.
This is a bright acoustic guitar sound.
This is a powerful acoustic guitar sound.
Adjusts the tone for the low frequency range.
Adjusts the tone for the middle frequency
range.
Adjusts the tone for the high frequency
range.

PHASER

By adding varied-phase portions to the direct sound, the phaser
effect gives a whooshing, swirling character to the sound.

EFFECT
Explanation
Adjusts the tone for the ultra high frequency
range.
Adjusts the volume.
Explanation
This is a four-phase effect. A light phaser
effect is obtained.
This is an eight-phase effect. It is a popular
phaser effect.
This is a twelve-phase effect. A deep phase
effect is obtained.
This is the phaser with two phase shift
circuits connected in series.
This sets the rate of the phaser effect.
* When set to BPM, the value of each
parameter will be set according to the
value of the "MASTER BPM" specified for
each patch. This makes it easier to achieve
effect sound settings that match the
tempo of the song.
* If, due to the tempo, the time is longer
than the range of allowable settings, it is
then synchronized to a period either 1/2
or 1/4 of that time.
Determines the depth of the phaser effect.
Determines the amount of resonance
(feedback). Increasing the value will
emphasize the effect, creating a more
unusual sound.
Adjusts the center frequency of the phaser
effect.
Adjusts the volume of the phaser.

Adjusts the center frequency at which to
apply the effect.
This sets the frequency at which the low
cut filter begins to take effect. When FLAT is
selected, the low cut filter will have no effect.
Adjusts the volume of the flanger.
