OVERVIEW
1. INSTRUMENT INPUTS:
The JX42 features four
1/4” instrument inputs for wired or wireless guitars.
Any combination of these four inputs can be active at
the same time, making it easy to switch instruments
from one song to the next. Large front-panel switches
turn each input on and off, and the input connections
are mirrored on the both the front and back of the
JX42 for convenience. The optional JR-5 remote
footswitch allows hands free operation and includes
LED indicators to show which guitars are active.
2. AMPLIFIER OUTPUTS:
A selector switch on the
front panel of the JX42 silently toggles between two
1/4” outputs to feed a pair of amplifiers. This feature
can also be accessed remotely using the optional
JR-2 footswitch. A pristine Class-A signal path and
Jensen transformer isolation on both outputs offer
studio quality sound while eliminating hum and buzz
caused by ground loops.
3. TUNER OUTPUTS:
The JX42 includes tuner
outputs on both the front and back panels. All inactive
instrument inputs automatically feed the tuner
outputs, so a guitar tech can simply grab and tune
without disrupting the performance. Both of the tuner
outputs can be used simultaneously.
4. MIDI INPUT:
Built in MIDI functionality allows you
to use third-party MIDI footswitches to control the
functions of the JX42 remotely. Instrument on/off
controls, amplifier switching, and the ability to have
both amplifiers on simultaneously are all available via
MIDI commands.

The JX42 V2 can be simplified by grouping its features into four main sections: the Instrument Inputs, the Amplifier
Outputs, the Tuner Outputs, and the MIDI Input.
