Congratulations on Your New
JangleBox JBX Compressor!
You’re probably a guitar player who won’t compromise on tone and
who demands pro-level compression. If so, your JangleBox JBX will
be your new, favorite pedal. The JBX will give you all the chime,
sustain and brilliance that JangleBox compressors are known for,
along with unrivaled tone-and-boost capabilities.
The JBX goes from the studio to the stage without missing a beat:
Dual mono outputs.
Separate, full EQ on both sides of the unit.
Preset treble-boost switch.
J-Boost gain switch for on-the-fly soloing or tonal variation.
True bypass.
Further refinements include moving the EQ circuit post-com-
pression for a quieter output, and eliminating microphonic
switch noise.
The advantages you’ll gain in power, flexibility and clarity will make
this one pedal in your rig that you’ll never turn o. The JBX is a com-
pression fan’s dream!
The JBX is Simple to Set Up
and Operate
As every guitar-and-amp combination is dierent for each guitarist, you’ll
want to experiment with the JBXsettings. We suggest first adjusting the
Bass and Treble to your desired tone, both on the regular side of the
compressor and the J-Boost side. Next, turn the Gain and Attack knobs to
the “12 o’clock” position, then tweak the volume and compression to your
satisfaction from there. Finally, adjust the J-Boost Gain to add (or lower)
volume and/or create a dierent tone.
The Gain settings adjust volume. The Attack setting adjusts the
intensity of compression. The Attack knob is common to both the
regular side of the JBX and the J-Boost side.
The T-Boost is a preset treble boost and is common to both sides of
the compressor. It will maintain the volume set either on the regular
side or J-Boost side.
The J-Boost switch is the second stage of the JBX. It can be used
for dierent tonal variations and/or up to a 20-25dB volume boost.
Adjust the J-Boost Gain for soloing, if desired. You can also activate
the J-Boost so that it comes on when you hit the On/O switch.
The J-Boost Gain, J-Boost Bass, and J-Boost Treble settings function
only when the J-Boost is switched on (blue light). See the back panel
for further explanation.
When daisy-chaining a series of additional pedal eects, you should
place the JBX first in the sequence (plug your guitar into the JBX) to
take full advantage of its true bypass.
Use any standard 9V pin-negative power source or the 9V battery
included with each unit. If you use a 9V battery to power your pedal,
compression will decrease as the battery wears. Remove the four
screws on the underside of the box to replace the battery.
