32 | ACOUSTIC FEEDBACK AND ACOUSTIC FEEDBACK DELUXE
This corresponds in the real world to a combination
of the distance between the speaker and guitar, but
also the volume of the amp. When set at the lowest
setting, it will only feedback on stable notes, and
when set at the highest setting, it will feedback on
most things, even noise or background hum.
Tolerance = MODERATE (Yellow): Feedback only
on very stable notes.
Tolerance = NORMAL (Green): Feedback on vi-
bratos, bends and slides. This usually gives the most
natural sounding feedback.
Tolerance = RAMPANT (Red): Wild and unpredict-
able feedback. Sometimes.
If you find it too hard to get feedback, you can do one of
three things:
1.
Increase the Feedback control (to make the
effect appear faster)
2.
Increase the Tolerance control (to make the
effect more tolerant towards note changes and
different playing techniques.
3.
Increase the input volume by increasing the
gain of your preamp or using a volume plug in
before Acoustic Feedback.
The timbre of the feedbacking tone will change slightly if
you change the
Tolerance
control during a feedback.
This can sound abrupt and unnatural, so it’s better to only
change the
Tolerance
when no note is feedbacking.
Tolerance Indicator
The Tolerance Indicator indicates when a feedback
is on its way, and when the feedback is about to
die. If the Tolerance Indicator starts to fade, make
sure that you end your note deliberately, before any
strange sounds appear. This is specially helpful when
you have a high Feedback or Tolerance setting.
Mix
Controls the balance between the feedback and the
original signal. Outputs only the clean guitar sound
when set on dry, and only the feedback effect when
set to WET.
Set this control so that the balance between the
guitar and the feedback sounds natural. This knob is
usually set somewhere in the green area.
Try playing around with
Mix
set fully on WET. You can
get some pretty interesting results from that...
Feedback
Controls how fast the feedback builds up. This cor-
responds in the real world to the volume of the real
amplifier. Low settings will give subtle harmonics,
and high settings will give an aggressive feedback.
Feedback = SUBTLE (Yellow area): The feedback
will usually not build up and the effect will be very
subtle.
Feedback = NATURAL (Green area): The feedback
will have a slow build up time and act quite natu-
rally, although it might be hard to get feedback on
all notes.
Feedback = WILD (Red area): The feedback will
have a faster build up time and it will be quite easy
to get the feedback effect on most notes, but some-
times it won’t sound very natural.
How the
Feedback
control works depends greatly on
your guitar, preamp, volume, what note you play etc.
Tolerance
Controls how easy it is to maintain the feedback
while changing notes, bending, doing vibratos etc.
