Features
The GRANITH GREY BOOSTER allows a high-quality
boost of up to +15dB with minimized switching
noise due to BJF engineered circuitry. This
booster is able to attain the equivalent S/N
ratio of a high-end amplifier. In order for this
to happen, the circuitry was created to fit the
frequency range of an electric guitar, which
lowers some overtones that coud otherwise be
present with other boosters.
Bjorn's Description:
A clean booster is simply a pedal that amplifies
signals. The concept is simple, however due to the
various uses for this type of pedal, it is a
complicated feat. What kind of booster is necessary
to maximize performance in any situation? We set
out on a quest to find the answer.
Granite is a rock whose name originated from the
Latin word Granum, which means "grain seed." It
was thus named Granith with the hope that this
product would send out strong roots into the world.
A booster is a pedal that amplifies incoming
signals. If the incoming signal has noise in it, the
noise is also amplified. This is an undeniable fact.
However, you don' t have to compromise by
thinking that this is unavoidable when you use a
booster.
Try a truly noiseless booster. A world you' ve never
experienced will unfold before you.
The One Control GRANITH GREY BOOSTER is thoroughly
dedicated to low noise. From the circuit design
stage, we tried to eliminate noise up to the limit of
possibility. After repeated consultations between
BJF and One Control, the booster now has a
completely newly-designed circuit by BJF. It is full
of BJF' s unique ideas that are unlike conventional
circuits.
It is full of BJF' s unique ideas that are unlike
conventional circuits. The case is made of high
quality cut-out aluminum to protect the precious
sound signals from inside and outside noises. It is
also much more durable than die cast cases.As a
result, the GRANITH GREY BOOSTER went beyond the
capabilities of a compact pedal and attained an S/N
ratio equivalent to a high-end vacuum tube audio
amp.
Relevant and Easy-to-Handle Boost
The One Control GRANITH GREY BOOSTER allows a
boost of +15dB. You might think this is nothing
extraordinary but we went through a number of
scenarios, all while maintaining the natural usability
of any equipment with any connection. If you turn
the level knob down to the minimum, you can mute
the sound and which allows you to set the level cut
and unity gain.
Pure Tone & Texture
The frequency characteristic of the GRANITH GREY
BOOSTER is unique. If you turn up the output without
changing the frequency characteristic of incoming
signals, you won' t be able to ignore the unnatural
'feeling' it creates. This discomfort is caused due to
at the original output level and the actual output
level. The GRANITH GREY BOOSTER creates the
necessary frequency characteristics while the
signal passes through the circuit. By doing so, the
GRANITH GREY BOOSTER realizes a pure and high
quality boost sound without compressing the sound
or narrowing the dynamic range.
Suitable For Any Guitar, Bass or Equipment
The One Control GRANITH GREY BOOSTER secured the
500kΩ input impedance to support any guitar and
bass.
ALL COPYRIGHT RESERVED BY LEP INTERNATIONAL CO., LTD. 2020
You can use it by directly connecting any guitars and
basses. From single to hum-bucking or from active to
passive, The GRANITH GREY BOOSTER does it all.Output
impedance was kept low up to 2kΩ at most, which fits
the amp.
Awakening Amp Potential
The One Control GRANITH GREY BOOSTER can be used
with any guitar amp. It not only pushes tube amps but
it is also suitable for boosting drive channels inside
transistor amps. It can also be used just like other
amps for analog circuits even when used with a
number of digital amps.
If you are using a high-gain amp, connecting the
GRANITH GREY BOOSTER to the e ect loop will allow the
volume to be boosted with power amp distortion all
while taking advantage of strong preamp distortion.
The GRANITH GREY BOOSTER will maximize the potential
of any amp to awaken its true capability.
Pedal Board Friendly
One Control introduced an original compact cut-out
aluminum case for the GRANITH GREY BOOSTER. The size
allows you to place it on any pedal board. Just like all
BJF Series FX pedals, it can be powered by a 9V
battery. Four PCBs inside the pedal secure the space
to hold the battery while preserving the standard mini
size. The power consumption is kept below 1mA to
allow longer battery power. The One Control GRANITH
GREY BOOSTER works with center negative 9VDC
adapters (EPA-2000 is recommended) or 006P 9V
batteries. When batteries need to be replaced the
distorted. The drive voltage of the GRANITH GREY
BOOSTER is set at higher than the normal level
(8.8-9.6V) to realize high quality sound. So the
batteries need to be replaced before they get down to
zero. Please use new batteries when you replace
them.
