ROGER MAYER VOODOO VIBE JR.
The Voodoo-Vibe Jr will faithfully reproduce all the old sounds and
incorporates the modifications I made for Jimi. The Supervibe was my
1st evolution of the Univibe and many leading performers including
Stevie Ray Vaughan and Robin Trower used this unit. The Voodoo-Vibe is
the 2nd evolution and also has a Tremolo circuit plus the usual Chorus
and Vibrato functions. The control of the sound parameters is greatly
expanded and is capable of producing many new unheard effects. The
Voodoo-Vibe Jr is the 3rd evolution and is the smaller brother of our
famous Voodoo-Vibe, which is used by so many great guitarists such as
Page and Clapton and still today remains the standard by which all
other Vibe type clones are judged. It has been designed in response to
the many requests of having a smaller unit with less knobs that still
gives the great tone of it's bigger and more complicated brother. The
Vibe Jr. has the same circuitry and configuration but does not have the
Tremolo function nor does it have the choice of sine or triangular
waveforms in three ranges and the symmetry controls.
The Voodoo-Vibe Jr is completely analogue in operation and exhibits a
very transparent and full sound quality that is lacking in digital
units that simulate chorus, flanging, phasing and vibrato effects. The
digital zipper noise and graininess is eliminated and the guitar tone
is maintained throughout the full dynamic range, Class A discrete
circuitry is used in all audio stages and results in ultra high audio
quality and very low noise. The signal to noise ratio of the unit is
102Db, which is about 12 Db better than a compact disc. Extensive power
supply filtering is used to ensure low noise operation from mains AC
adapters.
CONTROLS:
SPEED: The speed or rate of effect can be adjusted over a large range.
INTENSITY: The level of depth of the effect can be controlled and
is used in conjunction with the other controls to set up the final
effect.
SWEEP: This control enables the unit to be tuned to produce
different sweep effects from the Chorus and Vibrato mix. It changes the
frequency around which the unit sweeps (centre frequency). If the mix
control is set to full chorus the sweep can first be set to a good
starting point by turning the Intensity control to minimum and then
rotating the sweep control slowly whilst playing a chord until a
phasing or null is heard. This should occur at about the 2 o'clock
position of the sweep dial. Increase then the intensity control now and
a very typical Univibe effect will be heard. When the Mix control is
set at the full Vibrato setting the effects of the sweep control will
not be as great as this is a pitch shift effect.
MIX: This sets the mix or blend of chorus and vibrato effect.
QUICK START: Turning all the controls to the 12oclock position will
give a good starting point to begin experiencing the interplay of the
controls.
FEATURES:
MULTI-MODE OUTPUTS with HARD WIRE BYPASS or TWO BUFFERED OUTPUTS:
The Voodoo-Vibe Jr has three outputs, a true hard wire output plus two
buffered outputs that can drive long cable lengths with no high
frequency loss. These two buffered outputs are identical and are
disconnected when the hard wire output is being used. This means that
you have a choice for all possible performance or equipment situations
whether you feel a true hard wire output or buffered outputs will
perform best. In general the low output impedance of the buffer gives a
lower noise floor and a more punchy sound but now it's so easy to hear
the difference and make a real decision that is based on fact not hype.
MODE 1: There is no jack plug inserted into the Hard Wire Output (
HW OUT1 ).
The input of the buffer is connected through switching contacts on this
jack socket (HW OUT1) to the foot switching output ( "full bypass" or
"effect" ) and the two buffer outputs ( BF OUT2 ) and ( BF OUT3 ) will
thus follow the foot switching action. In this "bypass mode" however
the input of the buffer is only connected to the Input jack socket of
the unit and not to the Vibe circuit as well so it can be thought of as
"full bypass buffered".
MODE 2: When a jack is inserted into the Hard Wire Output (HW OUT1).
The input of the buffer is disconnected and no output signal will
appear at the two buffered outputs. The Hard Wire Output ( HW OUT1 )
will follow the foot switching output ( "full bypass" or "effect" ). In
this "bypass mode" the Hard Wire Output ( HW OUT1 ) is directly
connected to the Input jack socket and to nothing else in the unit and
is in "full bypass" - "true bypass" or "hard wire bypass" mode as the
input is directly connected to the output through the foot switch and
to nothing else.
LED : An LED shows the status of the effect. The LED also
shows a low battery condition and will fail to light in either status
thus showing that battery replacement is required.
RAPID BATTERY CHANGE : No more screws to loose!.. Slide the
front panel back and there is the battery. It could not be simpler or
faster. See picture below.
LONG BATTERY LIFE : Exceptionally low current consumption:
Bypass Mode=12mA. Effect Mode=15mA ensures an expected battery life of
more than 20Hrs with alkaline type batteries.
