SUSTAINIAMP OPERATION:
SWITCH CONTROLS:
POWER
switch: Turns the Sustain-man
ON
and
OFF
.
CHANGE HARMONICS
switch: Harmonic mode of string vibration is changed using the
CHANGE HARMONICS footswitch. Red/green LED changes color to indicate which mode is
selected.
MANUAL/AUTO/MAN
switch: Selects between MANUAL and AUTOMATIC operation.
(CHANGE HARMONICS FOOTSWITCH will force change of harmonic mode when switch is in
either position: MANUAL or AUTOMATIC.)
TURBO
switch: Increases string drive power. Makes sustain more intense. But it doubles the
battery current from about 50 ma to 100 ma.
HARMONIC MODES:
There are two HARMONIC MODES:
RED
HARMONIC
MODE, and
GREEN
HARMONIC MODE.
The two modes are indicated by the two-color HARMONICS OPERATION LED. This LED
illuminates either RED or GREEN, depending on which mode you are in. This visual indicator lets
you know what harmonic mode you are in. Both RED and GREEN modes are similar: Some notes
will fade into harmonics and some will vibrate as fundamentals. When you change modes,
fundamental notes will always fade into a harmonic. Harmonic notes will fade either into a
different harmonic or into a fundamental. Often, you will get several harmonics to occur in
sequence from the same note by simply changing mode over and over.
When the HARMONICS OPERATION slide switch is set to
MANUAL
, pressing the CHANGE
HARMONICS footswitch will change modes back and forth from
RED
to
GREEN
modes.
When the HARMONICS OPERATION slide switch is set to
AUTOMATIC
, you can simply release
fret pressure for an instant and the mode will change. Or, gently touch a vibrating string, or quickly
turn down guitar volume, then back up, and a note will automatically change harmonic modes. This
is a powerful feature. You can still use the MANUAL HARMONICS footswitch while in
AUTOMATIC mode of operation. This is a Maniac Music first.
A NOTE ABOUT AUTOMATIC MODE OPERATION:
Occasionally, a note will tend to rapidly
come to a stop rather than sustain. For these notes, the sustainer acoustic energy reaching the string
arrives "out of phase" with the string vibration because of the time it takes for the energy to travel
the distance to the fret from the Sustainiac transducer.
Usually
, in one mode or the other, about 2 or
3 notes on a guitar can have this characteristic. When this happens, the Sustainiac circuit senses
that a note is decaying rapidly, and automatically
forces
a harmonic mode change.
KNOB CONTROLS:
HARMONICS: Actually an equalizer. As the control is rotated toward "0", treble frequencies are
rolled off, and more fundamental notes will sustain. Rotating toward "10" means low frequencies
are rolled off, and notes will "
morph
" more easily into harmonics. Mid-rotation will sustain a
combination of both.
GAIN: Adjusts sustainer gain. More gain means faster sustain buildup, but it is harder to control
guitar. Doesn't change the amount of string drive, however.
STRING DRIVE: Adjusts signal level going to sustainer power amplifier (and overall gain).
Stronger sustained string vibration means more gain and faster sustain, but also harder to control
guitar.
