Applying an e ect

Chorus

1. Set each channel’s [CHORUS] switch to the WIDE or SPACE

position.

WIDE

This is a stereo chorus that processes the three bands

independently.

By applying band-appropriate chorusing to each of the low,

mid, and high-frequency bands, this e ect creates a deep and

spacious chorusing that is appropriate for the sound of an

acoustic guitar.

The low range remains  rmly localized in the center, and the

sound will become more spacious as you go from the mid to the

high range.

SPACE

This is a chorus that mixes the sounds in the air, a method that

is possible only with a stereo system. On the AC-33, the e ect

sound is emitted by the right speaker (as you face the unit), and

the direct sound is emitted by the left speaker. The chorus e ect

is produced as the sound from the left and right speakers is

mixed in the air.

Compared to an electrically mixed chorus e ect, this e ect

has a broader left/right spread and a more natural-sounding

spaciousness.

OFF No chorus e ect will be applied.

Turn the switch o if you don’t want to apply chorus.

Reverb/Ambience

1. Use the [REVERB/AMBIENCE] knob to adjust the amount of

e ect.

REVERB

This is a stereo reverb that was developed speci cally for

acoustic instruments and produces a spacious and natural

sound. The position of the knob adjusts the volume of the

reverb.

AMBIENCE

This e ect adds spatial depth. It produces a broader sound

 eld and a sense of presence.

The position of the knob adjusts the volume and depth of the

ambience.

REVERB AMBIENCE

The left half of the knob’s range applies reverb, and the right half

applies ambience.

Turning the knob toward the right will deepen the e ect.

If you want to turn reverb/ambience o , turn the knob all the way to

the left.

About foot switches

If you use a foot switch (BOSS FS-5U or FS-6; sold separately) you’ll be able to turn chorus on/o and reverb/ambience on/o with your foot.

If a foot switch is connected, the pedal(s) will operate as follows.

Refer to p. 9 for details on the foot switch’s polarity setting.

If you use a phone plug (mono) cable to connect only one foot switch,

it will only turn chorus on/o .

Chorus on/o operations apply in common to the GUITAR CHANNEL

and the MIC/LINE CHANNEL.

If the CHORUS switch is o , operating the foot switch will not turn the

e ect on/o .
