Vibezilla is an all new all analog vibe/tremolo inspired by
the original Unicord Uni-Vibe™ design, makes use of a
light bulb and photocells housed in a shielded light reflective
enclosure to retain the soulful qualities the original vibe
is known for. However, unlike the lossy discrete filters used
in the original vibe, the high-Q phasing filters in Vibezilla
use audio grade op-amps and caps which give more prominent and
deeper vibe sweep effects. Likewise, great attention was given
to the LFO sweep oscillator, lamp and flasher design. The primary
design goal of Vibezilla was to create a compact unit that truly
delivers giant sound with hypnotic throbbing vibe effects that
are musically and audibly addictive.
VIBEZILLA OVERVIEW
Vibezilla is an all new all analog vibe/tremolo
loosely based on the classic Unicord Uni-Vibe™ design.
Vibezilla, like the original vibe, makes use of a light bulb
and photocells housed in a shielded light reflective enclosure
to retain the soulful qualities the original vibe is known for.
However, unlike the lossy discrete filters used in the original
vibe, the high-Q phasing filters in Vibezilla use audio grade
op-amps and caps which give more prominent and deeper vibe sweep
effects. Likewise, great attention was given to the LFO sweep
oscillator, lamp and flasher design. The primary design goal
of Vibezilla was to create a compact unit that truly delivers
giant sound with hypnotic throbbing vibe effects that are musically
and audibly addictive.
Vibezilla was designed and constructed to meet
the needs of electric guitars and guitar players. A super high
impedance FET buffer input stage was added to prevent instrument
pickup loading and signal loss. The gain structure of Vibezilla
is completely adjustable via the input DRIVE control, output
level trimmer and internal gain range select DIP switch settings.
The adjustable DRIVE stage allows players to create driven vibe/phase
type sounds full of rich harmonics and detail. Vibezilla delivers
singing vibe tones and chords packed with more than enough soul
to easily obliterate lesser vibes.
NEW VIBE+TREMOLO
EFFECT!
Vibezilla contains an opto-tremolo (AM modulator) circuit that
can be combined with the phased vibe output or used separately.
By combining the vibe phase swept output with the tremolo modulator
output (Vibe+Trem mode), more realistic rotating speaker effects
are achieved. This combination phased vibe and tremolo action
allows the musician to generate huge throbbing and pulsating
type sounds previously unknown to vibe lovers. The wave SHAPE
switch modifies the sweep modulator waveform and adds even more
throb to the Vibe+Trem mode. New and experienced vibe lovers
alike should quickly become addicted to this new and powerful
phased tremolo effect!
PRO AUDIO HERITAGE
Vibezilla was designed, engineered and built to pro-audio standards.
We use high-quality long life conductive plastic pots, reliable
switches and true bypass relay switching. All SMD components
are modern hi-quality audio grade components combined with meticulous
PCB layout for stable low-noise operation. The signal path of
Vibezilla more closely resembles a high-end piece of studio
gear rather than any effect pedal. All capacitors are long-life
low impedance 105(C) audio grade types. Inside we use the same
level of detailed build standards that we use in our high-end
studio gear.

DUAL SPEEDS AND REMOTE CONTROL
Dual speed controls are selected by the SPEED A/B foot switch.
True bypass and remote effect bypass switching is achieved via
a small sealed telecom style relay. Blinking rate indicator
LED's indicate which A or B SPEED control is active at all times.
The external PEDAL jack allows a remote speed control pedal
(simple three wire interface - gnd, pot & switch) to enhance
and simplify vibe usage while playing. The dual speed controls
are available to allow players to quickly switch between two
speed settings (i.e. a fast and a slow rate) at times when a
speed pedal is not used or desired for maximum flexibility.
OPTO'S AND BULB FLASHER
Great effort and attention to detail went into the Vibezilla
low frequency oscillator (LFO) and lamp flasher design. Rather
than attempting to determine the original unknown bulb characteristics
and duplicate the quirky original vibe LF design, we sought
a better solution through design. Our lamp flasher LFO design
uses a special function generator IC with a servo mode lamp
driver amplifier that allows critical alignment and tweaking
of the bulb and element glow dynamics that ultimately dictate
the final vibe sound. A number of internal calibration trimmers
allow fine adjustment of the bulb current and glow dynamics.

The Vibezilla LFO design also closely
follows the non-linear amplitude response of the original
with respect to speed (i.e. as speed decreases the amplitude
of the LFO signal decreases). This LFO non-linearity "quirk"
is also key to the vibe sound and is what allows the effect
depth to gradually build up as the speed increases from
slow to near stopped rates. You'll also notice that the
DEPTH control has a big effect on the sound unlike the
original vibe; this is because our flasher will drive
the bulb intensity well beyond the range of the original
vibe LFO. The DEPTH control is typically used in the mid
position range for a closer match to the original Uni-Vibe
sound. At maximum DEPTH the vibe and tremolo circuit can
really squash the signal due to greater lamp intensity
available with the Vibezilla design. |
POWER SUPPLY
Vibezilla comes with an external 18V 300 mA DC wall wart supply
for maximum signal path, headroom and reliability. Internally,
Vibezilla operates at 15V and contains an onboard low-noise
linear regulator with thermal poly-fuse, protection diodes,
noise suppression inductor and plenty of bypass and filter caps
for super low noise operation. No noisy switching regulators
or boost converters are used in the Vibezilla.
