Anti-Feedback; Acoustic - Boss AD-5 Owner's Manual

ANTI-FEEDBACK

What anti-feedback does is reduce the howling
sound that can arise due to feedback between the
guitar and amplifier. The sound at frequencies
where howling occurs is compressed, thereby
suppressing the howl.
DEPTH
Adjusts the manner in which the anti-feedback
effect is applied. Turning the knob clockwise
suppresses howling more; turning it completely
counterclockwise turns the effect off.
* Whenever such howling is not a problem, or at times such
as when using the AD-5 during recording, set this to the
"Off" position.
FREQ (Frequency)
Adjusts the frequency at which the anti-feed-
back effect is applied. Turning the knob clock-
wise raises this frequency.
When howling occurs, rotate the Depth knob
completely clockwise, adjust the Frequency
knob to find the position that reduces the howl-
ing, then turn the Depth knob counterclock-
wise to the point just before howling again
begins to occur.

ACOUSTIC

With this feature, you can change the sound from
a pickup on an electric-acoustic guitar into a
richer sound, similar to that obtained by a micro-
phone placed near a guitar.
BODY
This simulates the characteristic resonance in-
side the body of an acoustic guitar. The nature
of this resonance changes according to the con-
trol setting position, so determine your own
preferred setting to match the guitar you use.
Turn the knob completely counterclockwise
turns the effect off.
MIC DISTANCE
This simulates the distance between the micro-
phone capturing the sound of an acoustic guitar
and the guitar itself. Turning the control clock-
wise creates a sound obtained by placing the
microphone at a greater distance; turning it
completely counterclockwise turns the effect
off.
