VJR9 Vintage Jet Riser
FEATURES AND CONTROLS
●Vintage Jet Riser VJR9 is a contemporary version of 70s legendary JETLYZER JL-70.
●Employs newly-developed Jet sound generator. Internally generated jet signals are processed
in VCA (voltage-controlled amplifier) and VCF (voltage-controlled filter), and then mixed with
inputted guitar sound source. Jet sound is generated by analog flanger circuit using BBD
(bucket brigade device) and high-performance NR (noise reduction).
●Wide range of effects, such as heavy/deep jet sound and chorus-like tremolo sound, are
available.
●By using an external footswitch, jet sound is turned ON and OFF. VJR9 can be used as a
flanger when jet sound is OFF.
●Employs DC to DC converter circuit and internal voltage stabilization circuit. Battery voltage
drop and fluctuation of AC power source do not affect sound quality and function.
①IN (input jack)
Input jack to connect to the output of guitar, other effects or re-
lated equipment. The product automatically turns on when a
plug is inserted into this jack. When not in use, disconnect plug
from input jack to preserve battery life. It is recommended to
place a distortion or overdrive guitar effect just before VJR9 for
better jet sound effect.
②OUT (output jack)
Output jack to connect to input of amplifier or other effects.
③FOOT SW. (external footswitch jack)
A jack to connect an external footswitch. Jet sound ON and
OFF is switchable with external footswitch. (Use a general-

nals is approx. 70Hz. As guitar input signals in-
crease, it changes to approx. 2kHz at maximum.
Jet effect is adjusted by the following three con-
trols; RANGE, SENSITIVITY and JET. These con-
trols are mutually related. When either one of these
controls is turned fully counterclockwise, no jet
sound is available. If there is no guitar signal, no jet
sound is outputted.
⑤JET
Controls volume of jet sound generator. Turn it
clockwise for larger volume. No jet sound is avail-
able in the fully counterclockwise position. VJR9
can be used as a flanger in the fully clockwise po-
sition.

output characteristic of your guitar and/or perform-
ance. Turn it clockwise for high sensitivity.
⑦SPEED
Controls modulation speed. Turn this knob clock-
wise for faster modulation.
⑧WIDTH
Controls modulation depth. Turn this knob clock-
wise for deeper modulation. No modulation is
available in the fully clockwise position.

tery condition. At the battery operation, it lights
when plug is inserted to input jack and effect is
on. At the external power supply (AC adaptor) op-
eration, it lights when effect is on. No LED light
indicates the battery is low or not installed. In this
case replace the battery with a new one.
⑪DC INPUT
